Explanation:

Neutrophils are a type of white - blood cell that play a crucial role in the body's immune response to fight off infections. They are the most abundant type of white blood cell and are quick to respond to sites of infection. Erythrocytes are red blood cells and are not white blood cells. Thrombocytes are platelets involved in blood clotting. Lymphocytes are also white blood cells but are more associated with long - term immunity and specific immune responses rather than the immediate fight against infections like neutrophils.

Answer:

C. Neutrophils
