The energy source on Voyager 2 is not a nuclear reactor, in which atoms are actively broken apart; rather a kind of nuclear battery that uses natural radioactive decay to produce power.
A. apart; rather
B. apart, but rather
C. apart, but rather that of
D. apart, but that of
E. apart; it is that of

正确答案B.
我选择了A, 不太明白A\B之间的真正区别，另外But前面是个句子，后面不也应该连个句子才对么？
大家一起讨论下呢？

这题考的是平行，not A, but (rather) B是固定搭配。
