B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: C
Solution :
Option [c] is correct. Explanation: Charge carries flows through whole cross-section. So, the filed exists both inside and outside. So, the assertion is true and the reason is false.
