B
Correct answer
Explanation
The default directory where Informatica PowerCenter stores cache files for Aggregator, Lookup, and Joiner transformations is designated by the system variable $PMCacheDir. Other choices like $CachePMDir are not standard system variables, and $PMDir represents the general repository root path rather than the specific cache folder.
