Question

the sun releases energy in what form? electrical mechanical light

Explanation:

The Sun releases energy mainly in the form of light (solar radiation). Through nuclear fusion in its core, it produces electromagnetic radiation which includes visible light. Electrical energy is not the main form released by the Sun. Mechanical energy (like motion - related energy in a traditional sense) is also not the primary form. The Sun's energy reaches Earth as light (solar energy) which is then converted into other forms (like thermal energy when it heats the Earth's surface) but the initial form of release is light.

Answer:

C. light
