Which statement is true about a black hole?

A. It is a very small hole having extreme gravity.
B. It has a maximum temperature at its core region.
C. It has a huge-sized invisible body with extreme gravity to hold light.
D. It is a very small black region with huge mass and extreme gravity.



Answer :

Final answer:

A black hole is a gravitational region where even light cannot escape, formed by the collapse of a star. The extreme gravity of a black hole is due to its high density and small size.


Explanation:

A black hole is a region of space where gravity is so strong that even light cannot escape from it. It is formed when a star collapses under its own weight, becoming extremely dense. The size of a black hole is very small compared to its mass, making it have a strong gravitational pull.
