Sentence Correction (SC) | Re: After working for two hours, the essay started to take shape

Nooo, we definitely can't use "he" without an antecedent on the GMAT. B is the only answer that isn't grammatically wrong, and this would be a fine sentence in the context of a larger piece of writing (in which we would presumably know who "he" is), but this would never fly on the GMAT.
