- APure linear motion.
- BPure rotational motion.
- CBoth linear and rotational motion.
- DNo motion.
Explanation:

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.
