Question

which of the following white blood cells fight parasitic infections?
a eosinophils
b basophils
c monocytes
d lymphocytes

Explanation:

Eosinophils are a type of white blood cell that play a key role in combating parasitic infections. Basophils are involved in allergic reactions and inflammation. Monocytes are part of the immune system's response to pathogens and can differentiate into macrophages. Lymphocytes are involved in adaptive immunity (e.g., B and T cells for antibody production and cell - mediated immunity). So among the given options, eosinophils are the white blood cells that fight parasitic infections.

Answer:

A. Eosinophils
