• A bullet embedded in a block

• Collision of two glass ball

• none of the above

C.

Collision of two glass ball

Inelastic collision:- The deformation may not be relieved and the two bodies could move together after the collision. A collision in which two particles move together after the collision is called completely inelastic collision. Collision in which momentum of the system is conserved but not the kinetic energy are called inelastic collisions. In the above cases, collision of two glass ball is an inelastic collision.
