I got D.
let's see how I got that.
A. it is infering too much. going out of scope
B. it never says that, it simply says that some insects that survive after reproducing for the first time, can be useful to ecosystem. Probably some are not useful as well. the ones that die, some of them can be useful as well...no information has been provided regarding that.... so it is out.
C. See the word "May"
that means bees may or may not survive...
D. This one is exactly what we can infer. some bees may die, but some survives, that can be surely infered from the argument.
E. is out of scope.
