Assertion (A): The resistivity of a material is independent of the dimensions of the conductor. | Reason (R): The resistivity is a material property that depends only on the type of material and its temperature.
A
Both A and R are true and R is the correct explanation of A.
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
