C. Learning about the base-rate fallacy.
Incorrect.
The base rate fallacy which is defined by Myers as "the
tendency to ignore or under use base-rate information (information that
describes most people) and instead to be influenced by distinctive features
of the case being judged," is not related to the overconfidence phenomenon.
The base-rate fallacy is much more closely related to the representativeness
heuristic (see Myers, pg. 110).
