Answer 1

The correct option is C

Light

• An explanation for the correct option

(C) Light-Candle wax is a carbon-based compound derived from petroleum. During combustion, the wax burns to give heat and light in addition to carbon dioxide and water released in the form of steam. Since combustion is a reaction where the wax reacts with oxygen, it can be said that the fuel is oxidized.

• The explanation for the incorrect Options

(A) Energy- When the wax gets burnt it gives the heat and light energy not only energy.

(B) Force- To push or pull any object is called force and it is not produced on burning the wax.

(D) Torch- It is a source of light.

Hence, option (C) is correct as when coal get burnt it gives the heat similarly when wax gets burnt gives light.
