Human Immunodeficiency Virus (HIV) causes the immune system to which of the following?

Human Immunodeficiency Virus (HIV) causes the immune system to which of the following?

• A. Speed up
• B. Break down
• C. Work efficiently
• D. Continue working properly

Answer: (B)

HIV targets and weakens the immune system by attacking CD4 T cells, which are the key coordinators of immune responses. As these cells are destroyed, the body has fewer troops to recognize and fight off infections, so the overall immune defense breaks down. This makes the body more susceptible to infections and illnesses that a healthy immune system would usually handle. The other options describe the immune system functioning more strongly or efficiently, which HIV does not do; it impairs and undermines immune function.
