Sentence Correction (SC) | Re: A mutual fund having billions of dollars in assets will

This question can be simply tackled by (1) pronoun mismatch & 2.) , + Verbing denoting cause and effect.

C,D & E are out as "they" are being used for the singular subject " A mutual fund company)
B is out for using atleast and more at the same time.
A is the answer, which is rightly depicting the cause & effect relationship by using VerbING.
