  1. The rate of change of momentum is equal to the force applied

  3. The body is rest until a force is applied

  4. The body is tend to be rotated if the force is applied tangentially

B Correct answer
Explanation

The requirement of the third law is important in the equilibrium of the body. Specially the rigid bodies. The rigid body particles are in the equilibrium and are thus facing the forces and to be in the equilibrium they also react and apply the opposite force and thus the third law of newton.
