Detailed Solution

Moment of inertia of a body is directly proportional to the mass of the body. More body mass equals a greater moment of inertia.

Moment of inertia changes as a body's axis of rotation shifts. A body will have different moments of inertia about different axes.

It is not dependent on the angular velocity as well as the time period of the body.

Hence the correct answer is A and B are correct.
