ANSWER
Hypersegmented neutrophil. When stained, neutrophils have a segmented nucleus and pink/orange cytoplasm under light microscope. The majority of neutrophils have three nuclear segments (lobes) connected by tapering chromatin strands. A small percentage have four lobes, and occasionally five lobes may be seen.
Eosinophils usually have bilobed nuclei
Basophilic granulocytes have a 2 or 3 lobed nucleus. The lobes are usually not as well defined as in neutrophilic granulocytes and the nucleus may appear S-shaped.
Monocytes have one large nucleus, which is usually centrally placed within the cell and often kidney shaped
