Statement-1 : Kinetic energy is conserved in both, perfectly elastic and perfectly inelastic collisions.
Statement-2 : Because linear momentum is conserved in both.

Options

A. Statement - 1 is ture , statement -2 is true, and statement-2 is correct explanation of statement -1.
B. Statement-1 if ture, statement-2 is true, but statement -2 is not a correct explanation of statement-1.
C. Statement-1 is true, but statement -2 is false.
D. Statement-1 is false, but statement-2 is true.

Answer
