First of all, let's think about the scientific method, and its processes of how it works.
It all starts with observation, so we need to check all the data we have and all the information that can be collected to have a good thought on what's going on.
After gathering enough information, let's think about a hypothesis that could help solving this problem. Well, reading the question, we can check that that region passed through the wettest summer in 100 years, and that's the main problem here, because before this weather, was this disease a problem? I guess not, so this can be a reason, the change in the percentage of water in the air.
With that said, we need to test if this is true or not, and for that, we'll need mosquitoes with the West Nile virus, and we'll put them in different environments, one that it's wet, and another one that it's not that wet, just like the West Nile problem. This way we can check if this is the problem or not, if it's affecting their reproduction and etc.

Explanation:
DNA is the genetic material and transfer from one generation to the generation. The DNA composed of the nitrogenous bases, pentose sugar and the phosphate group.
The base pairing of DNA follows the Chargaff's rule. According to this, the purines an pyrimidine ratio is equal to 1. The number of adenine is equal with that of thymine and number of cytosine is equal to the guanosine. In option (A) this criteria is follows.
Thus, the correct answer is option (A).
Atmosphere and climate. There are several hypotheses about the nature and cause of the Carboniferous Rainforest Collapse, some of which include climate change. ... The carboniferous period is characterised by the formation of coal deposits which were formed within a context of the removal of atmospheric carbon.
