GWD 2 的一道语法

Minivans carry as many as seven passengers and, compared with most sport utility vehicles, cost less, get better gas mileage, allow passengers to get in and out more easily, and have a smoother ride.



A.
            Minivans carry as many as seven passengers and, compared with most sport utility vehicles, cost less,

B.
            Minivans, which carry as many as seven passengers, compared with most sport utility vehicles, they cost less,

C.
            Minivans carry as many as seven passengers, in comparison with most sport utility vehicles, and have a lower cost, they

D.
            Minivans, carrying as many as seven passengers, compared with most sport utility vehicles, cost less,

E.
            Minivans, which carry as many as seven passengers, compared with most sport utility vehicles the cost is lower, and they

这道题在A，D中犹豫不决，A 中 动词平行的话, 应该只有一个and吧？可是省去插入语，是carry and cost, get, allow and  have...?

而D选项也不对，carrying的话改变了原句的初衷，变成M和其他vehicle在载七个人的情况下比较..

求大家指点指点

个人感觉是选a

第一个and是并列两个句子，我们可以补全整句话为：

Minivans carry as many as seven passengers and, compared with most sport utility vehicles,  Minivans cost less, get better gas mileage, allow passengers to get in and out more easily, and have a smoother ride.

其中compared with most sport utility vehicles,  Minivans cost less, get better gas mileage, allow passengers to get in and out more easily, and have a smoother ride

是另外一句话，因为很明显，第一句话的装几个人，和同什么比更经济什么的，是两个并列的意思，应该用两段

我理解你的意思， 我的问题是 Compared with most SUVs,minivans carry as many as 7 passengers and cost less, get...., ....and 

这里有两个and  这样的用法可以吗？？
