3. Millions of female bats rear their pups in Bracken Cave. Although the mothers all leave the cave nightly, on their return each mother is almost always swiftly reunited with her own pup. Since the bat's calls are their only means of finding one another, and a bat pup cannot distinguish the call of its mother from that of any other adult bat, it is clear that each mother bat can recoguize the call of her pup.

The argument seeks to do which of the following?

A) derive a general conlusion about all members of a group from facts known about reqresentative members of that group.
B) establish the validity of one explanation for a phenomenon by excluding alternative explanations.
C) support, by describing a suitable mechanism, the hypothesis that a certain phenomenon can occur
D) conclude that members of two groups are likely to share a certain ability because of other characteristic they share
E) demonstrate that a general rule applies in a particular case.

Why is C wrong???

B should be the right answer since the argument excludes alternative explanation (a bat pup cannot recognize her mothers call so mother must recognize the pup's call) to arrive to the conclusion that the female bat should recognize pup's call.
