The correct answer is B. m2.
Moment of inertia is a measure of how difficult it is to change the rotation of a body. It is calculated by multiplying the mass of an object by the square of its distance from the axis of rotation. The SI unit of moment of inertia is the kilogram-meter squared (kg m2).
Option A, m, is the unit of mass. Mass is a measure of how much matter is in an object.
Option C, m3, is the unit of volume. Volume is a measure of how much space an object takes up.
Option D, m4, is not a valid unit.
