Which is a possible reason for the relatively quick spread of the shown disease

Give the following choices;

A. An abiotic factor.

B. a decreased food supply.

C. increased population density

The answer is; C

High population densities increase the rate of spread of disease. This is why to control a highly contagious disease, policymakers in public health discourage public gatherings The major reason for the quick spread of the disease is because of the shorter distance of hop from one person to the other in crowded places. Lack of sanitation and some social behavior (such as shaking of hands) aggravate this spread.

it's unlikely a majority of a large population would agree on issues

hope this : )
