B.the shuttle and earlier spacecraft, with sufficient enough power in fuel cells and batteries for their short flights

C.the short flights of the shuttle and earlier spacecraft, which enabled them to carry sufficient enough power in fuel cells and batteries

D.the shuttle and earlier spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights

哎，我开始一看题也选错了，不过猜测应该是因为With修饰上会产生歧义吧，D中的which后面接了were可以避免这种歧义

gmatziyu

with会引起歧义呢？？不明白。。。

切尔西

with可以修饰the shuttle and earlier spacecraft整体，也可以单独修饰spacecraft

gmatziyu

继续困惑中。。

sufficient enough有点重复,而且即使要一起应该也是
sufficiently enough吧

如果用with的话，容易引起歧义，因为可能修饰的是spacecraft，也可能是the shuttle and earlier spacecraft，
而earlier spacecraft是单数，which were就避免了这一歧义。

同意楼上观点
with在这里却是有可能引起奇异
which were好些
