Answer to Question 1

ANS: B
The correct maturation sequence is myeloblast, promyelocyte, myelocyte, metamyelocyte, band, segmented.

Answer to Question 2

ANS: A
The description fits that of a myeloblast. Often the myeloblast is agranular (without any visible granules), although special cytochemical staining can demonstrate the presence of myeloperoxidase in the cytoplasm even when granules are not present or visible.
