But in choice A, the construction is:
BOSSY VERB+prepositional phrase+THAT+Subject+Command Subjunctive
prepositional phrases are MODIFIERS, and are therefore "middlemen" (i.e., they can be eliminated from the overall sentence structure). provided that they are placed logically (so that they don't destroy clarity), they exert no forces on the underlying structure of the sentence.
therefore, the insertion of the prepositional phrase, in this case, doesn't affect the integrity of the sentence structure at all.
