Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In a polar substance, in the absence of an external electric field, the material exhibits zero net dipole moment. Reason (R): A non-polar molecule develops an induced dipole moment only when placed in an external electric field. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. is true but (R) is false.
4. is false but (R) is true.
