In my opinion E is incorrect because it makes a comparsion between number (7 people) and people.
If you substitute choice E, this is how it would look: Only seven people this century have been killed by the great white shark, the man-eater of the movies, fewer than the ones killed by bee stings.

agree, at first I am not very sure about what are compared here. Indeed, I think the number of people killed by shark is compared to the number of people killed by bees, not people. and ones cannot mean the number.
