Hello Nida,
The choice of engineering branch depends solely on your own interest.
Below mentioned are the reasons:
1. Market conditions vary every 6 months to 1 year. Engineering is a 4 year course. There is a high chance that the field which looks the most promising at the time of taking admission might not be good when you complete engineering.
2. Engineering mostly involves practical skills rather than theoretical knowledge. If you choose a stream based on market trends, chances are that you might not be able to understand the subject properly. This may result in lesser grades and impact on practical skills.
I hope it helps. If so, kindly upvote this answer. If you have any further questions, kindly revert.

10+2 with PCM (Physics, Chemistry and Mathematics) is the basic requirement to take admission in engineering programme.
The percentage required in qualifying exam is 60% and JEE Mains for most of the engineering institutes. However, the required percentage criterion depends on the college. IITs consider JEE Advanced.
There are several entrance exams in India at national and state level. Among them, JEE Mains is the most sought-after engineering entrance test. Some private institutes like BITS Pilani, VIT, LPU University etc. conduct their separate entrance test.
The best colleges are:
DTU,
BITS
College of Engineering, Pune
Lovely Professional University
Hindustan Institute of Engineering Technology, Chennai
Vellore Institute of Technology
P. S. G. College of Technology, Coimbatore
Madras Institute of Technology, Chennai
SCMS School of Engineering and Technology, Cochin
Veermata Jijabai Technological Institute, Mumbai
Anna University
College of Engineering, Pune.

Yes, BBA+MBA at LPU is a very good option for career prospects. It would be a good choice to opt for LPU as in the present scenario this is the university that caters to the all-around development of its students and nurtures it with care to boost the career to a pinnacle of ultimate success which might be the envy of many. I would say the Integrated course at LPU not just saves a year but is financially compatible as well. As per my view, LPU has an edge in terms of curriculum, exposures, and placements. Integrated BBA MBA is a 4-year programme. LPU has been ranked 34 in the Management ranking in 2022 by the National Institutional Ranking Framework (NIRF). The Business School of LPU is accredited by ACBSP, Accreditation Council for Business Schools and Programs from the USA ensuring quality education and industry-experienced faculty members.

Hello Parth,
Object-Oriented Programming is a methodology or paradigm to design a program using classes and objects. It simplifies the software development and maintenance by providing some concepts:
Object
Class
Inheritance
Polymorphism
Abstraction
Encapsulation
Object
Any entity that has state and behavior is known as an object. For example: chair, pen, table, keyboard, bike etc. It can be physical and logical.
Class
Collection of objects is called class. It is a logical entity.
Inheritance
When one object acquires all the properties and behaviours of parent object I.e. known as inheritance. It provides code reusability. It is used to achieve runtime polymorphism.
Polymorphism
When one task is performed by different ways I.e. known as polymorphism. For example: to convince the customer differently, to draw something e.g. shape or rectangle etc.
In java, we use method overloading and method overriding to achieve polymorphism.
Abstraction
Hiding internal details and showing functionality is known as abstraction. For example: phone call, we don't know the internal processing.
In java, we use abstract class and interface to achieve abstraction.
Encapsulation
Binding (or wrapping) code and data together into a single unit is known as encapsulation. For example: capsule, it is wrapped with different medicines.
A java class is the example of encapsulation. Java bean is the fully encapsulated class because all the data members are private here.

After B.Sc. You can go for M.Sc. Or other courses and then Ph.D. if you want to be a hardcore researcher. For which you have to start preparing for NET/SET (SLET) competitive exams as CSIR conducts this NET twice in a year. Just remember that this is the toughest and tricky kind of exam. But once qualified, life will be easy and smooth, as you will be getting fellowship worth 25,000 Rs. Per month. Most popular colleges for doing M.Sc. Are:
University of Hyderabad-School of Life Sciences, University of Mumbai-Institute of Chemical Technology, National Dairy Research Institute
Rajiv Gandhi Center for Biotechnology
School of Allied Medical Sciences, Lovely Professional University
Delhi Technological University-Department of Biotechnology, Indian Institute of Technology-Department of Biochemical Engineering & Biotechnology, Delhi University.
