B) If both the assertion and reason are true but reason does not explain the assertion.
C) If assertion is true but reason is false.
D) If assertion is false but reason is true.
Correct Answer: D
Solution :
When an electric field is applied to the dielectric, each molecule of dielectric gets polarised i.e., centres of gravity of positive and negative charges get displaced from each other. On the left face, a net negative charge \[-{{q}_{i}}\], and on the right face, a positive charge\[+{{q}_{i}}\],appears. Thus. electric dipoles are produced inside. This is the dielectric polarisation.
