D

Verified step by step guidance1
Step 1: Understand the role of HIV in the human body. HIV (Human Immunodeficiency Virus) is a virus that primarily targets the immune system, weakening the body's ability to fight infections and diseases.
Step 2: Identify the specific type of immune cells targeted by HIV. HIV specifically attacks CD4+ T cells, which are a type of white blood cell crucial for coordinating the immune response.
Step 3: Clarify the function of CD4+ T cells. These cells act as 'helper' cells, signaling other immune cells like B cells and cytotoxic T cells to respond to infections.
Step 4: Compare CD4+ T cells to the other options provided. Red blood cells are not part of the immune system; they transport oxygen. B cells produce antibodies, but they are not the primary target of HIV. Neurons are nerve cells and are unrelated to the immune system.
Step 5: Conclude that CD4+ T cells are the correct answer because they are the primary cells targeted and attacked by HIV, leading to immune system dysfunction.
