题目：
One summer, floods covered low-lying garlic fields situated in a region with a large mosquito population. Since mosquitoes lay their eggs in standing water, flooded fields would normally attract mosquitoes, yet no mosquitoes were found in the fields. Diallyl sulfide, a major component of garlic, is known to repel several species of insects, including mosquitoes, so it is likely that diallyl sulfide from the garlic repelled the mosquitoes.
Which of the following, if true, most strengthens the argument?
Which of the following, if true, most strengthens the argument?
选项:
A、Diallyl sulfide is also found in onions but at concentrations lower than in garlic.
B、The mosquito population of the region as a whole was significantly smaller during the year in which the flooding took place than it had been in previous years.
C、By the end of the summer, most of the garlic plants in the flooded fields had been killed by waterborne fungi.
D、Many insect species not repelled by diallyl sulfide were found in the flooded garlic fields throughout the summer.
E、Mosquitoes are known to be susceptible to toxins in plants other than garlic, such as marigolds.

提问：
OG的讲解说A是无关的，但是我觉得有点他因削弱的意思。onions也有ds说明不一定是大蒜造成的了。
OG说E是他因削弱可以理解，蚊子除了对大蒜敏感还会对其他敏感，所以有可能是其他因素导致。
还想问一下支持和削弱都算有关吗？要怎么区分选项是有关无关呢？
