For which virus is the mosquito not known as a possible vector?

Explanation:
Mosquitoes serve as vectors for viruses that rely on the mosquito-to-human transmission cycle, known as arboviruses. West Nile Virus, Zika, and Dengue are all transmitted by mosquitoes (such as Aedes species for Zika and Dengue, and Culex for West Nile), making the mosquito a key part of their spread. Smallpox, on the other hand, is caused by variola virus and spreads primarily through respiratory droplets and close contact between people, with no role for mosquitoes in its transmission. Therefore, the mosquito is not a known vector for smallpox, which is why that option is the correct choice.
