Which of the following is a classical example of an exocrine multicellular gland?

Explanation:
Glands that are exocrine multicellular have a secretory portion organized into cells and a duct system that carries the product to an epithelial surface. Sweat glands are a classic example because they are multicellular structures with a secretory portion in the dermis and a duct that transports sweat to the skin surface, producing a secretion onto the body’s exterior. In contrast, the pituitary, thyroid, and adrenal glands are endocrine glands. They lack ducts and release hormones directly into the bloodstream to act at distant targets, rather than secreting onto a surface.
