Q1. Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: A circular disc with mass 'M' and radius 'R' was determined to have moment of inertia about the X, Y (passing through its plane) and Z (perpendicular to its plane) axes of lx, ly, and Iz, respectively. For each of the three axes, the corresponding radii of gyration will be identical.

Reason R: A rigid body making rotational motion has fixed mass and shape.

Select the best response from the following options in light of the statements above:

Both A and R are correct but R is NOT the correct explanation of A.
A is correct but R is not correct.
A is not correct but R is correct.
Both A and R are correct and R is the correct explanation of A.
