Assertion (A): When we change the unit of measurement of a quantity, its numerical value changes.

Reason (R): Smaller the unit of measurement smaller is its numerical value.
(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.
