Investigate the impact population density has on the spread of disease.(which is correct)

Overcrowding in densely populated areas can cause sanitation issues and human-animal interactions that can spread diseases quickly.

Overcrowding in densely populated areas can cause large movements of people and the spread of diseases.

Overcrowding in densely populated areas can cause sanitation issues, and human-animal interactions that can slow disease spread.

Overcrowding in densely populated areas can cause sanitation issues that stop the spread of disease.

The correct statement is:

Overcrowding in densely populated areas can cause sanitation issues and human-animal interactions that can spread diseases quickly.

High population density can lead to overcrowding, inadequate sanitation infrastructure, and increased interactions between humans and animals, all of which can contribute to the rapid spread of infectious diseases. These conditions create environments that are conducive to the transmission of diseases such as respiratory infections, diarrheal diseases, and vector-borne diseases. Additionally, crowded living conditions can make it difficult to implement effective public health measures to control the spread of disease.
