Solution
The correct option is D Hypopharynx A pair of salivary glands is placed on either side of the crop. Each gland has two glandular portions and a bag like a reservoir. From the glandular portions of the two sides, many ducts arise which unite to form a common duct. The common duct opens at the base of the hypopharynx.
