Can you please explain why it is option B but not option A?

Torque = moment of inertia* angular acceleration.

Torque ( force applied to rotate an object).
Moment of inertia ( resistance offered by the body against rotation).
angular acceleration ( change in angular velocity of an object).
by Newton's 2nd law F= ma. Here T= la.
