Given below two statements : One is labeled as Assertion (A) and other is labeled as Reason (R).
Assertion (A) : Non-polar materials do not have any permanent dipole moment.
Reason (R) : When a non-polar material is placed in an electric field, the centre of the positive charge distribution of it’s individual atom or molecule coincides with the centre of the negativne charge distribution .
In the light of above statements, choose the most appropriate answer from the options given below:

In the light of above statements, choose the most appropriate answer from the options given below:
Option 1 -
Both (A) and (R) are corrected and (R) is the correct explanation of (A).
Option 2 -
Both (A) and (R) are connected and (R) is not the correct explanation of (A).
Option 3 -
A) is correct but (R) is not correct.
Option 4 -
A) is not correct but (R) is correct.

Correct Option - 4
Detailed Solution:In non-polar molecules, centre of +ve charge coincides with centre of –ve charge, Hence, net dipole moment becomes zero.
When non-polar material is placed in external field, centre of charge does not coincide, hence give non-zero moment.
