同A选项有相同错误，the short flights 和 space station 没有可比性，which引导的定语从句有问题，spacecraft enable them（指什么？）to carry.逻辑意思不通。them指什么不知道~

C. 比较对象错误同A；which有enable的约束指代了short flights没问题，但them指代不清晰；Sufficient和enough同义词重复。

比较对象不对等，Unlike后的关键字是the short flights，而比较对象是a space station

sufficient跟enough語意重複。them 指代不清(不知道是指short flights 還是unlike 後面整體)。比較對象不對等，變成是用short flights跟space station 比較。
