In an attempt to explain the cause of malaria, a deadly infectious disease, early European settlers in Hong Kong attributed the malady to poisonous gases supposedly emanating from low-lying swampland. In the 1880s, however, doctors determined that Anopheles mosquitoes were responsible for transmitting the disease to humans after observing that the female of the species can carry a parasitic protozoan that is passed on to unsuspecting humans when a mosquito feasts on a person's blood.

The boldface part is the evidence that formed the basis for scientists' new understanding that "Anopheles mosquitoes were responsible for transmitting [malaria] to humans". (Technically the passage states only a time order, not a cause/effect relationship—"doctors determined xxxxx after observing that..."—but, with a bit of common sense combined with the way the scientific method always works, we can infer that the latter is the evidential basis for the former.) So that's choice A.
My main gripe with the phrasing of the correct answer is that it should say "It provides support for AN explanation of a particular phenomenon" or "It provides support for ONE explanation of a particular phenomenon". The passage actually presents two explanations (and DOESN'T confirm that the second explanation is the only currently accepted one!), so "THE explanation" makes no sense here.

Completely agree, the statement in the boldface is an explanation. That boldface does not give support to any other explanation, it is itself the explanation.
