C Correct answer
Explanation

Black holes have such intense gravitational field due to their extremely high density (mass concentrated in a tiny volume) that nothing, not even radiation or light, can escape from beyond the event horizon. The escape velocity exceeds the speed of light. The size of a black hole (event horizon) depends on its mass, but the key property is the density. Small or large size alone doesn't create a black hole - it's the mass-to-volume ratio (density) that matters.
