Which of the following most logically completes the passage?

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 ______.

Alarge moths are generally able to maneuver better in flight than smaller moths
Blarge moths are proportionally much more common in warm climates than in cool climates
Csmall moths are more likely than large moths to be effectively camouflaged while on vegetation
Dlarge moths typically have wings that are larger in proportion to their body size than smaller moths do
Emost predators of moths prey not only on several different species of moth but also on various species of other insects

正确答案: B

I think the logic is weird. None of the answer is right. Just can pick B in comparison.

The more reasonable answer should be such as 'which explains why under normal temperature, large moth survives less than or as many as small moth'

right?

同感，当时做这题时，看完题目，脑子里就跳出这个答案，很自信地把五个选项都看了一遍，结果发现一个都不对，结果就紧张了，又把题目看一遍，后来才选B，浪费好多时间
