The correct option is C Bowman's glands
Bowman's glands are branched tubular glands in the olfactory mucous membrane. The structure of the Bowman's glands consists of an acinus in the lamina propria and a secretory duct going out through the olfactory epithelium. Bowman's glands secrete proteins, such as lysozyme, amylase and IgA similar to serous glands.
