According to my gf's lsat professor - A) is the correct answer - Thinkblue's explanation below is the correct one.
I myself, chose B, because I didn't think that other insects were in the scope of the argument.
Thinkblue makes a good point that even though it's not talking directly about Bees, it doesn't necessarily means it's out of scope. Option A says Other insects have the
similar vision as bees - so that would technically level the playing field when comparing other insects and bees.

A.
The question is asking for evidence in favor of the conclusion (paraphrased) flowers evolved to suit bees, instead of bees evolving to suit flowers.
Option A says that other insects have the same vision as bees, but they don't use it to differentiate colors.
Which MEANS that that type of vision did not evolve for the purpose of distinguishing colors.
Which MEANS bees vision can differentiate colors and flowers evolved to suit that purpose, and not the other way around.
Also, mention of other insects does not automatically mean out of scope. Many GMAT questions refer to elements not mentioned in the question stem (eg: there is one on this forum in fact, something to do with global warming and destruction of coastal cities, and the correct answer mentions technology).
