B Correct answer
Explanation

From the perspective of an observer on Earth, someone falling into a black hole appears to slow down as they approach the event horizon due to gravitational time dilation, and seems to take infinite time to cross it. This is called infinite redshift. Option B correctly describes this relativistic effect. Options A, C, and D are incorrect.
