Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators. In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.
A. large moths are generally able to maneuver better in flight than smaller moths
B. large moths are proportionally much more common in warm climates than in cool climates
C. small moths are more likely than large moths to be effectively camouflaged while on vegetation
D. large moths typically have wings that are larger in proportion to their body size than smaller moths do
E. most predators of moths prey not only on several different species of moth but also on various species of other insects
Not convinced why B and why not c

Is the OA really A? If so this question is pretty weak or the OA is a typo or something, because A does not make sense.
The prompt goes on about how each moth has an optimal temperature for effective flight and then discusses that if the moths are not flying, they have to sit on vegetation, where they are vulnerable to predators.
Answer choice A dispenses with most of that and goes into basically another topic, implying that because of their higher body temperature, larger moths can maneuver better. Where did that come from and why would what A says even be the case?
At the same time, choice C does not work either.
The fact that large moths have higher optimal body temperatures does not explain why smaller moths would be more likely to be effectively camouflaged. In fact the opposite would make more sense. If they were operating in the same climate as smaller moths, larger moths would need more effective camouflage, because when temperatures fell, the larger moths, which require higher temperatures for flying, would be more likely to be stuck waiting for temperatures to go back up.
Choice D does not seem in any way connected to body temperature.
Choice E does not follow from the prompt.
What does make sense is choice B, which fits the prompt in that since large moths need higher temperatures to fly and thereby make themselves safer from predators, large moths would be proportionally more common in warmer climates.
On another forum I saw about five people in a row choose choice B. You might want to send a quick note to whomever you got this question from to make them aware of the issue with the OA.

My bad the answer is indeed B . It was a Typo from my side.
Thank you so much Marty . I understood why was it B too.

LOL. That explains it.
To top it off, in another thread someone else also said that the OA is A, and someone went on to explain why, in detail. I was like in the Twilight Zone.
