36 feet is being modidfied , so eliminate A, D E.

Left with B and C , we need "and" here so that 36 feet is not wrongly modified .

IMO C.

Answer is C
The present infinitive expresses contemporaneous action (an action happening at the same time as another action):

I am happy to be president.

In the sentence above, I am happy (in the present) to be president (also in the present).

The present perfect infinitive expresses past action:

I am happy to have been president.

In the sentence above, I am happy (in the present) to have been president (in the past).

In the SC above, the reptile no longer exists, so the present perfect infinitive is needed:

...the Quetzalcoatlus...is believed to have been the largest flying creature the world has ever seen.

The correct answer is C.
