I know this one has already been discussed, but my doubt has not been clarified yet.
OA is D. However, in D, "they" refers to suppliers (the subject); and that would be incorrect. Could anybody clarify?
To meet the rising marketing demand for fish and seafood, suppliers are
growing fish twice as fast as their natural growth rate, cutting their feed
by nearly half and raising them on special diets.
A. their natural growth rate, cutting their feed allotment
B. their natural growth rate, their feed allotment cut
C. growing them naturally, cutting their feed allotment
D. they grow naturally, cutting their feed allotment
E. they grow naturally, with their feed allotment cut
