Show answer & explanation
Correct answer: D
A black hole is theoretically defined as a perfect absorber of all electromagnetic radiation due to its extreme gravitational pull. Consequently, it reflects absolutely no light or energy from its surroundings back into the universe. This physical property implies that the reflection coefficient must be exactly zero.
