@ROn : The choice C has people in it "a population of only 4 million people" . AnD OG says the reference of them is unclear. i am completely lost, why it will not be the case because " them " has only one reference "people" ?
One thing i've found is that the GMAT does not often allow antecedents that are buried deep in the sentence. "people" is buried under three layers of prepositions and is therefore not going to be your antecedent here. Keep in mind though that the GMAT's explanations for SC problems are often unsatisfying, and although their ANSWERS are always correct by definition, their EXPLANATIONS often leave a lot to be desired. The important thing to note here is that C is wrong for other reasons..
Although there are other problem in this ans choice i.e C, most of the time object of the preposition is not LIKELY (only "likely" correct?) to be the antecedent of the pronoun.. but in this case there is nothing in the sentence that can stand for THEM so can we consider PEOPLE as the correct antecedent!?
