Solution

The correct option is D Total energy and momentum are conserved but kinetic energy is not conserved

$=>$ Kinetic energy is not conserved in an inelastic collision,
but that is because it is converted to another form of energy (heat, etc.).
$=>$ The sum of all types of energy (including kinetic) is the same before
and after the collision.

MY PROBLEM
According to book Answer is (b) [both are true but reason is not the explanation of assertion]
Assertion is true but I think reason is false because Energy is conserved only in elastic collision and in Reason it is not mentioned whether it is elastic or inelastic.
