If an observer were to pass inward through the event horizon of a black hole, they could
A) do nothing to prevent themselves from falling directly into the singularity at the center.
B) escape again provided that the black hole is spinning.
C) move outward within the black hole with a powerful rocket, thereby avoiding the singularity until their fuel ran out, but they could never escape back out through the event horizon.
D) avoid the singularity by going into orbit around it, but they could never move outward again from any particular orbit.
