in a collision of two bodies whether it is perfectly elastic or inelastic linear momentum is always conserved but KE need not be conserved. so ans is false

in elastic collision final relative velocity is equal to initial relative velocity hence kinetic energy is conserved

coefficient of restitution (e) = 1 no energy loss as collision is perfectly elastic. Hence, conservation of kinetic energy will obviously hold true!
