‘Black hole’ is a
huge black star which has zero acceleration due to gravity on its surface
star which has moderate acceleration due to gravity on its surface
star which has collapsed into itself and has large acceleration due to gravity on its surface
star which has collapsed into itself and has zero acceleration due to gravity on its surface
Answer is Right!
Answer is Wrong!

UPSC NDA-1 – 2019
– This collapse compresses the mass into an extremely small volume, resulting in incredibly dense matter.
– The gravitational pull becomes so strong that nothing, not even light, can escape from within a certain boundary called the event horizon.
– The “surface” (event horizon) of a black hole is characterized by an extremely large acceleration due to gravity (often conceptualized by the escape velocity exceeding the speed of light).
– Options A, B, and D are incorrect because a black hole is not a typical star, and it has extremely large, not zero or moderate, acceleration due to gravity at its boundary.
