select the correct answer.
which statement is true about prolonged exposure to stress?
a. it weakens the immune system.
b. it strengthens the immune system.
c. it does not affect the immune system.

Explanation:

Prolonged stress is known to have negative impacts on the immune system. Chronic stress can lead to the release of stress hormones like cortisol, which over time can suppress immune function, weakening the body's ability to fight off infections and illnesses. So option A is correct as it aligns with the understanding of stress - immune system interactions, while options B (stressing strengthening immunity) and C (stressing having no effect on immunity) are incorrect.

Answer:

A. It weakens the immune system.
