c eosinophils
d basophils

Explanation:

Polymorphonuclear leukocytes (PMNs) are a type of white blood cell (leukocyte) that have a segmented nucleus. Neutrophils, eosinophils, and basophils are all types of granulocytes. Neutrophils are the most abundant type of PMNs. Lymphocytes are agranulocytes and have a round nucleus, not a segmented one. Eosinophils and basophils are also granulocytes but are not as commonly referred to as PMNs as neutrophils.

Answer:

A. Neutrophils
