Hi Kranti, Well it would depend on your personal choice and that can not be suggested by any one else. However, you can always opt for a subject that you have studied in your education or anytime previously, as this will act as an advantage in your exams with a chance to score well. As mentioned by

you can choose phy, chem, or electrical subject
