One Consequence of the No-Hair Theorem ("Black Holes Have No

One consequence of the no-hair theorem ("Black holes have no hair") is that:

A) matter that falls into a black hole does not retain any measurable properties at all, when observed by an outside observer.
B) matter that falls into a black hole retains no properties except its mass, as measured by an outside observer.
C) certain kinds and shapes of matter (i.e., long strings) cannot fall into a black hole.
D) matter that falls into a black hole does not retain any properties except its mass, spin, and electric charge, as measured by an outside observer.
