The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths-2,500 to 3,000 feet down.
(A) on account of living
(B) on account of their living
(C) because it lives
(D) because of living
(E) being they live
Why the correct answer is "because it lives"? I think that The golden crab refers to many individuals, therefore the correct answer must be "because they live".

In the GMAT, when in doubt choose Singular. It is true that it is referring to specie of golden crabs but the sentence refers to the crabs collectively... So you must use singular
