Yes, C is better option

(A) believed to be - incorrectly placed modifier, closer to wingspan than to reptile.
(B) and that is believed to be - ambiguous use of that, not referring to the reptile
(C) and it is believed to have been - correct
(D) which was, it is believed, - use of was and is together. sounds awkward
(E) which is believed to be - sounds like wingspan is believed to be....

i think the question stem has to be corrected a little bit..

A huge flying reptile that died out with the dinosaurs some 65 million years ago,
the Quetzalcoatlus had a wingspan of 36 feet,
believed to be the largest flying creature the world has ever seen.

There shud be comma after "the Quetzalcoatlus " to make it a complete statement..

any thoughts?

I think option C is wrong because "it" can refer to either Quetzalcoatlus or wingspan. I really like the structure in option A for 1 main reason. I'll give you an example to explain what I mean:

1) The dog loves food, treated with great care and love.
explanation: because we have a comma after "food", "treated," which is a past participle, refers to the subject of the previous clause. So that subject of the previous clause is "The dog."

2) The dog loves food treated with great care and love.
explanation: because we DON'T have a comma after "food", "treated," which is a past participle, refers to the closest noun or to the attached noun. So that would be "food."

The first example is the logical choice! So that is the same reasoning I used to pick option A as my choice.

What's OA?

(A) believed to be---Seems awkard by to be , yet I think it is best answer.
(B) and that is believed to be-- That has no referent as which . Since which and that modifies the word that precede.
(C) and it is believed to have been--- Ask your self what is believed the Wingspan of Quetzalcoatlus or Quetzalcoatlus? No clear referent of it.
(D) which was, it is believed,Wrong since which has no clear referent
(E) which is believed to beb]Wrong since which has no clear referent[/b]

I'm not agree with OA , however this question needs to be clarified by an expert .

this option uses "Have been"...which I feel is incorrect....have is a plural verb form
also have been...is incorrect use of tense....the animal lived in the past...and it is already gone

have in 'to have' is an auxiliary verb for infinitive form

have for 'perfect aspect'
be for 'used to form the passive voice and continuous aspect)

had a hard time between A and C, but after reading it again, A has the same problem as E, what is believed modifying? wingspan or the creature?

C because of the use of "and"...by parallelism, "it" refers back to the creature... but could anybody explain whether the usage of "have been" is right here?

A: Awkward.
D and E: Which needs to be directly behind Quetzalcoatlus to be grammatically correct.
B: "That" refers to The Quetzalcoatlus having a wingspan of 36 feet and does not refer to the reptile itself.
C: "It" refers to the Quetzalcoatlus. Present perfect "have been" is correct because the reptile was the largest flying creature 65 million years ago and still is the largest flying creature at the present moment. Correct.

I would go with C.

(A) believed to be - verb is missing
(B) and that is believed to be - what is "that" referring here.
(C) and it is believed to have been - Correct
(D) which was, it is believed, - wrong placement of which
(E) which is believed to be - wrong placement of which

(A) believed to be
(B) and that is believed to be
(C) and it is believed to have been
(D) which was, it is believed
(E) which is believed to be

C for me

A D and E - misplaced modifier - the phrases should modify the Quetzalcoatlus rather than a wingspan of 36 feet
B : that has no clear antecedent

I go with C
In this case "and it is believed to have been the largest..."
its not a normal present perfect verb....thers no verb ahead of it.. ..."to have been" here indicates some kind of compulsion ..."must"

"Have is often combined with an infinitive to form an auxiliary whose meaning is similar to "must."

I will go with C too.

D and E are out because of "which" - which refers to the noun immediately preceding it.

A is wrong, because you are joining 2 independent clauses without a conjunction and it also does not have a verb

B is wrong because of "that"

Only C is left.

I'm not agree with OA , however this question needs to be clarified by an expert .

(C) and it is believed to have been --- if we assume that it could refer to wingspan then we cannot compare a wingspan to the largest creature. So it has to refer to Quetzalcoatlus only. Have been means that the belief is still valid that the reptile is largest flying creature.

C seems to be right, even though 'have been' is considered wordy by gmat.
The problem with the sentence is that it is missing a FANBOYS conjunction after the comma. [IMO]
We need to add an 'and' after the comma to make it a proper dependent sentence and only C is doing that.
So by POE, I would go for C on the test day any day.

Of all the options, C appeals to me more.
"and it is..." introduces a new clause, which emphasizes a new characteristics of the flying reptile.
Furthermore, "believed to have been..." rightly suggests that the reptile is still the largest
creature ever know to date.

A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of 36 feet, and it is believed to have been the largest flying creature the world has ever seen.

The present perfect in 'have been the largest' means that so far, there wasn't a bigger flying creature. It does not mean that the creature lives today (in fact, it was extincted long ago), but the world hasn't seen a larger flying creature until now.
