Hi Khodi7531,
Since this is a Flaw question we need the answer choice to describe something that is specifically laid out in the argument. Answer A is more of a possible flaw than an absolute flaw. You stated that "He uses pianists to conclude that all musical instruments alter brain structure." But the argument says: "...This shows that practicing on, and playing, a musical instrument actually alters brain structure." Technically, the only instrument the argument is referring to is the piano. It is possible that the argument is trying to make a more general statement about all instruments, but since this is a flaw we are not looking for possible errors, we are looking for errors that are specifically stated within the stimulus.
As you stated, the error here is causal. The author assumes: Cause- Being a highly skilled musician (through practice), Effect- Enlarged area of the brain. But it could have been the reverse: Cause- Enlarged area of the brain, Effect- Being a highly skilled musician (through practice). This leads to Answer B.
Hope that helps!
