Question

which activity will best help prevent the common cold?

a. washing your hands

b. wearing sandals in public showers

c. washing food

d. getting vaccinated

Explanation:

The common cold is often spread through contact with contaminated surfaces and then touching the face. Washing hands regularly removes germs, reducing the chance of infection. Wearing sandals in public showers prevents fungal infections (like athlete's foot) not colds. Washing food is for food - borne illness prevention. There's no vaccine for the common cold as it's caused by many viruses. So handwashing is the best prevention method.

Answer:

A. Washing your hands
