Final Answer :
A
Explanation :
Psychoneuroimmunologists believe that stress can weaken the body's immune system, making it more susceptible to illness. This is supported by research that shows stress hormones can interfere with immune system function, leading to reduced protection against viruses and bacteria. Stress has also been linked to the development of chronic diseases such as heart disease and cancer.
