“B” is iffy in my eyes because it says clearly he is in posession of material, non public information, which you are forbidden to act on, or cause others to act on. ”

It is a tricky question (and my guess is it is from Schweser), but I think the key is that the information was actually public information, he just first heard it from a nonpublic source. But again, focus should be that the information was not “nonpublic” when he heard it, so mosaic theory is not really applicable here.
