126. As envisioned by researchers, commercial farming of lobsters will enable fisheries to sell the shellfish year-round, taking advantage of off-season demand, standardize its sizes and colors, and to predict sales volume in advance.

(A) taking advantage of off-season demand, standardize
(B) taking advantage of off-season demand, to standardize
(C) taking advantage of off-season demand, standardizing
(D) take advantage of off-season demand, standardizing
(E) take advantage of off-season demand, to standardize

Solution:

Parallelism*

The underlined part “taking advantage of off-season demand “ is a subordinate clause of “will enable fisheries to sell the shellfish year-round” and hence, should have the ‘ing form’. Hence, D and E can be eliminated.
“will enable fisheries to sell…to standardize…and to predict” is the parallel structure.
Hence, A and C can be eliminated.
Thus, B is the best choice.
