In option D, I was confused what is the Antecedent for THEY. I thought Argentine Ant was the Subject and we needed a Singular. Could someone please help me understand this.

Hello, babloorudra. I am glad to help you with this one. It confused me at first, too, but when I considered the alternatives, (D) was a clear winner. Pick it up from the underlined portion, and consider the because clause to be a dependent introductory clause, as though the rest of the line were a standalone sentence, and the answer makes complete sense:

(D) because they are so genetically similar to one another, the ants consider all their fellows to be close relatives and thus do not engage in the kind of fierce intercolony struggles that limit...

Since struggles is, of course, plural, the only other reasonable option at the tail-end of the underlined portion is (B), but it has other issues. Even if you are unsure about the due to versus because split, notice the lack of clarity in referring to a bunch of different ants as a singular close relative.

(B) due to its being so genetically similar the ant considers all its fellows to be a close relative and thus does not engage in the kind of fierce intercolony struggles that limit...

Does this mean the ant thinks of different ants it encounters as a specific relative, say, Cousin Eddy or whatever, or does it perceive that these different ants are related to it in general, which the sentence seems to be driving at? A quick fix in close relatives would tidy that one up, but in any case, there is no such problem anywhere in (D).

I hope that helps. If you have further questions, please let me know. Good luck with your studies.
