Answer : The correct option is, Inelastic Collision
Explanation :
There are two type of collision.
(1) Elastic collision
(2) Inelastic collision
Elastic collision : In this collision, there is no loss of kinetic energy in the system. In this, both kinetic energy and the momentum remains conserved.
Inelastic collision : In this collision, there is a loss of kinetic energy in the system. In this, the momentum remains conserved but kinetic energy is not conserved. The kinetic energy transformed into another type of energy.
Hitting a baseball with a bat is a type of an inelastic collision due to the loss of the friction, sound and heat energy.
Hence, the correct option is, Inelastic Collision
