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
E. movies, fewer than the ones

my answer is B but OA is E. Actually E sounds so bad to me and B seems plain and correct. can anyone tell me where my mistake is? thanks.
