Guys i am expecting some healthy reasoning, reasoning like why a particular op is wrong and one is correct...my struggling and have some confusion thats y..

8416

Now, as per my observation, the choice should be between C & E, i had posted D earlier, my mistake.
C seems incorrect to me because "those" seems to refer to adults, which cannot be twice, they can be twice the number.

Please help me understand the below sentence.

Researchers claim to have developed new "nano-papers" incorporating tiny cellulose fibers, which they allege give them the strength of cast iron.

The above sentence is from mgmat sc. Contextually, "they" must refer to Researchers (as they is used to refer to living things) and "them" to nano papers ( as nano papers are the things being developed which get cast iron strength).

So the sentence seems to be correct but as per the guide it is wrong as the antecedents they and them may refer to any of the nouns. Please explain this as any other noun will not fit in here.
