D Correct answer
Explanation

The gravitational pull of a black hole is so strong that nothing can escape once past the event horizon - not even light or electromagnetic radiation. The escape velocity exceeds the speed of light. Hawking radiation theoretically allows very slow energy loss, but this is negligible - practically, nothing escapes.
