An Area Within the Superior Temporal Sulcus Is Involved in Processing

An area within the superior temporal sulcus is involved in processing biological motion. We know this because

A) neurons within this area are robustly activated by viewing point-light animation sequences depicting
Biological motion.
B) neurons within this area are not activated by viewing the same sequences in which the dots have been scrambled in position.
C) neurons within this area are not activated by viewing dot animations portraying nonbiological objects.
D) all of these
