Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Net dipole moment of a polar linear isotropic dielectric substance is not zero even in the absence of an external electric field. Reason (R) : In absence of an external electric field, the different permanent dipoles of a polar dielectric substance are oriented in random directions. In the light of the above statements, choose the most appropriate answer from the options given below :
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A) 2.
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is not correct but (R) is correct
- D(A) is correct but (R) is not correct
