Assertion : Moment of inertia is always constant. Reason : Angular moment is conserved that is why moment of inertia is constant.

A
If both assertion and reason are true and 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 reason is false.
Correct answer
D
If both assertion and reason are false.

Solution

The moment of inertia is not a fixed quantity but depends on the orientation and position of the axis of rotation with respect to the body as a whole.

Hence, the correct answer is option: 'D'.
