Assertion: The numerical value of a parameter changes when the unit of measurement is changed.
Reason: Smaller the unit, smaller is the numerical value.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
C. If Assertion is true but the Reason is false
D. If both Assertion and Reason are false

Answer

C

Explanation

If `n_(1)` and `n_(2)` are the numerical values corresponding to units `u_(1)` and `u_(2)` for the measurement of a parameter `P` then `P=n_(1)u_(1)=n_(2)u_(2)impliesn alpha 1/u` . The larger unit has the smaller value.
