Solution

The correct option is C
$C h e m i c a l e n e r g y \to H e a t e n e r g y + L i g h t e n e r g y$

The head of the matchstick consists of combustible substances which possess stored energy, i.e., chemical energy. When a matchstick is rubbed against a suitable surface the combustible substances start to burn with the evolution of heat and light energy. Thus, chemical energy stored within combustible substances of matchstick transforms into heat and light energy.
