比较结构中时态也要求对等么？

最近在翻就题，发发现了一个新的问题
Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by bee stings.

A.movies—less than those

B.movies—fewer than have been

C.movies, which is less than those

D.movies, a number lower than the people(B)

E.movies, fewer than the ones

这道大白鲨大家应该很熟悉吧
今天分析B,E的时候，发现他们还存在一个时态的不同
B是have been killed by bee stings， E是killed by bee stings.
是不是比较级也讲究时态的对等所以选了个跟之前的have been killed by the great white shark很对等的B？
