When the total weight of a shipment is increased, it is either accompanied by an increase in freight charges, or a delay in delivery time, as shipping companies may choose a slower and cheaper mode of transportation.
(A) When the total weight of a shipment is increased, it is either accompanied by an increase in freight charges, or (a delay)
(B) When the total weight of a shipment is increased, it is accompanied either by an increase in freight charges or
(C) When the total weight of a shipment is increased, the increase is either accompanied by an increase in freight charges or by
(D) Any increase in the total weight of a shipment is accompanied by either an increase in freight charges, or by
(E) Any increase in the total weight of a shipment is accompanied either by an increase in freight charges or by
The only parallel option is option is E, hence is the correct answer.
either X or Y is a parallel structure => X and Y must must match. So if I say "either by something" the next part must be "or by something else".
If I say "either accompanied by" the next part must be "or verb by" and so on
Hope it's clear
