arth's sun, and a supernova explosion must have occurred. B. The star must be 29 times larger than Earth's sun, and a supernova explosion must not have occurred. C. The star must be 29 times larger than Earth's sun, and a supernova explosion must have occurred. D. The star must be 10 to 28 times larger than Earth's sun, and a supernova explosion must not have occurred.
The star must be 29 times larger than Earth's sun, and a supernova explosion must have occurred.
Explanation:
A black hole is a giant, gaseous and huge structure present in the space.In physical appearance, it ca be 29 times more massive and bulky than the sun. The black hole pulls energy and matter from the surrounding galaxies and is becoming enormous in size day by day.
Moreover, a black hole pulls light from its surrounding matter with so much gravity that it gets trapped and can not escape from it. Stellar is a kind of black hole which emerges when a big star collapses or falls in automatically. When it occurs an exploding star "supernova" is formed which bursts out into an explosion.

Oxygen is needed to break the sugar into carbon dioxide, releasing energy the plants can use to stay alive. However, plants also take in energy from the sun(light), carbon dioxide from the atmosphere, and water from the soil; they use all of them in order to make sugar, and release oxygen.
