b. immediately becomes less sickly less foul tempered more engaged with the world and more independent
I literally just took the test and yes b. immediately becomes less sickly less foul tempered and more engaged with the world and more independent is the answer. It is incomplete because you don't know who the sentence is talking about. There are two parts to a sentence. The subject and the predicate. If a sentence is missing one of the two factors, it is incomplete. Subject describes the who, what, or where and the predicate describes what that noun is doing. Anyways, hope this helps and have a great rest of your day!
