Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Moment of inertia of a circular disc of mass 'M' and radius 'R' about X, Y axes (passing through its plane) and Z-axis which is perpendicular to its plane were found to be `I_(x),I_(y)` and `I_(z)`respectively. The respective radii of gyration about all the three axes will be the same. Reason R : A rigid body making rotational motion has fixed mass and shape. In the light of the above statements, choose the most appropriate answer from the options given below :

A

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

B

A is not correct but R is correct.

C

A is correct but R is not correct.

D

Both A and R are correct and R is the correct explanation of A.
