Summary Introduction

Introduction

Stress can affect the functioning of our body's immune system. The field of psychoneuroimmunology investigates how psychological factors can impact our immune system's ability to function. Measuring the presence of properties in the blood that help compose the immune system, researchers have been able to assess the connection between stress and immune system function.

Explanation of Solution

Correct answer and explanation

The best answer is (A), in which stress is most likely going to weaken Boris's immune system. Stress can potentially harm the functioning of our body's immune system, which in turn tends to increase our likelihood of developing health problems. Research reveals that stress tends to suppress the function of our body's immune system. This has been measured by studying the presence of properties in the blood composing the immune system. Thus, stress is most likely to weaken Boris's immune system function.

Explanation for incorrect statements

Option (B) refers to strengthening the immune system. However, research reveals no such correlation, but rather shows how stress can negatively impact immune functioning. So, option (b) is incorrect.

Option (C) refers to the immune system being unaffected. However, psychoneuroimmunology has indeed revealed a connection between stress and immune functioning. So, option (c) is incorrect.

Option (D) refers to none of the above. However, research actually demonstrates that chronic stress can gradually weaken immune system functioning. So, option (d) is incorrect.

Therefore, the options (B), (C), and (D) are incorrect.
