Assertion (A): The method of dimensions analysis cannot validate the exact relationship between physical quantities in any equation.

Reason (R): It does not distinguish between the physical quantities having same dimensions.
(1) Assertion (A) is true, Reason (R) is true; Reason (R) is a correct explanation for Assertion (A).
(2) Assertion (A) is true, Reason (R) is true; Reason (R) is not a correct explanation for Assertion (A).
(3) Assertion (A) is true, Reason (R) is false.
(4) Assertion (A) is false, Reason (R) is true.
