The Answer is B Mosquitoes

Explanation:

Because The first yellow fever outbreaks in the United States occurred in late 1690s. Nearly 100 years later, in the late summer of 1793, refugees from a yellow fever epidemic in the Caribbean fled to Philadelphia. Within weeks, people throughout the city were experiencing symptoms. By the middle of October, 100 people were dying from the virus every day. Caring for the victims so strained public services that the local city government collapsed. Philadelphia was also the seat of the United States government at the time, but federal authorities simply evacuated the city in face of the raging epidemic.

Eventually, a cold front eliminated Philadelphia’s mosquito population and the death toll fell to 20 per day by October 26. Today, a vaccine prevents yellow fever in much of the world, though thousands of people still die every year from the disease.
