Correct Answer : (3) Supernova is an exploding Star.

Explanation:

A supernova is a stellar explosion that is more energetic than a nova. It happens when a star has reached the end of its life and explodes in a brilliant burst of light.

Supernova can briefly outshine entire galaxies and During this short interval it can radiate as much energy as the Sun is expected to emit over its entire life span. They’re also the primary source of heavy elements in the universe. According to NASA, supernova are “the largest explosion that takes place in space.”

The explosion expels much or all of a star’s material at a velocity of up to 30,000 km/s (10% of the speed of light).
