Question

this image shows someone practicing good hygiene. what does this hygiene practice help prevent? smelling unwanted body odors the transmission of disease exposure to toxic chemicals the spread of common pests

Explanation:

Practicing good hygiene, such as covering the mouth and nose when sneezing (as shown in the image), is a key measure in preventing the spread of germs. Disease transmission often occurs through respiratory droplets. By covering the face during sneezing, these droplets are contained, reducing the likelihood of others inhaling or coming into contact with the pathogens they carry. Unwanted body odors are more related to personal cleaning (like bathing, using deodorant) rather than sneezing hygiene. Exposure to toxic chemicals is about avoiding harmful substances in the environment (e.g., wearing protective gear when handling chemicals), not sneezing. The spread of common pests (like insects, rodents) is managed through pest - control methods (traps, pesticides, keeping areas clean of food sources that attract pests), not sneezing hygiene.

Answer:

the transmission of disease
