In A, believed to be is modifying feet not the Quetzalcoatlus

In B , that is not clear what it refers to

in D and E, which is referring to feet/wing but not to Quetzalcoatlus

My Answer is C. (here it clear refers to Quetzalcoatlus )

From a thread on this question the other day:
D and E use a relative clause (starting with "which"), but the clause appears to modify "wingspan." It's not the wingspan that is believed to be the largest flying creature.

A creates a run-on sentence; we need a subject to go with the verb "believed"

B uses a conjunction to link the clauses, but we still don't have a subject for "believed"

C successfully creates two clauses: "the Quezalcoatlus had a wingspan..., and it is believed..."
I love dinosaur questions :D

Hi Bill,
I have one doubt in "B" option. Can't we consider "that" as a subject of the second clause similar as we are taking "it" as a subject in "C" option. please elaborate on this.

Thanks in advance.

Abhishek

I suppose you could, but "that" is nearly always used as a conjunction on the GMAT.

If you use "that" as a subject for the second clause, you run into a reference error. "That" could refer to "Quetzalcoatlus" or "wingspan."
