Solution

The correct option is C
$C h e m i c a l e n e r g y \to M e c h a n i c a l e n e r g y \to S o u n d e n e r g y$

While playing clapping game (Hand clap) both Sunil and Kavita move their alternate hands at the same instance and makes contact with their hands (clap) which produces sound. This is because the energy stored in the body, i.e., chemical energy (obtained from food) is required for the movement of our hands (mechanical energy) which finally converts to sound energy.
