Answer
Correct option: A.
Mucous gland
(a) Mucous gland Explanation: Mucous glands are exocrine glands that have ducts. They secrete mucous, which is released into various parts of the body such as the digestive and respiratory tracts. In contrast, the pituitary, thyroid, and parathyroid glands are endocrine glands, which secrete their hormones directly into the bloodstream and do not have ducts.
