A 25-year-old male presents with recurrent respiratory infections. Which immune component is most likely deficient?

Correct Answer: B cells

Step 1: Understand that recurrent respiratory infections mean the person gets sick often, especially with lung or breathing problems.
Step 2: Know that the immune system has different parts that help fight infections, including B cells.
Step 3: Recognize that B cells are responsible for making antibodies, which are proteins that help fight off infections.
Step 4: Realize that if someone has a problem with their B cells, they may not produce enough antibodies.
Step 5: Conclude that the most likely deficiency in this case is related to B cells, leading to inadequate antibody production.

B Cell Deficiency – B cell deficiencies result in reduced antibody production, making individuals more susceptible to infections, particularly respiratory ones.
