A) Ignore the non-essential modifier "compared with most SUV", A) reads "Minivans carry seven passengers, cost less, get better gas mileage, allow passengers to get in and out more easily, and have a smoother ride."

verb "carry" are paralleled to a list of verb, namely "cost", "get", "allow", and "have".

B)"Minivans they cost less" incorrect
C) "Minivans carry...and have a lower cost, they...." Sentence fragment, incorrect
D)noun, + modifier1, +modifier2; modifier2 "compared with most sport utility vehicles, cost less" incorrectly modifies "passengers" in modifier1
E) same as D
