Which of the following is a type of exocrine gland?

Explanation:
Exocrine glands release secretions onto surfaces or cavities through ducts, while endocrine glands release hormones into the bloodstream. Merocrine secretion involves vesicles fusing with the cell membrane to release contents by exocytosis, with the cell remaining intact. This exocrine mode—secretions exit via ducts without losing the cell—fits the definition of an exocrine gland. Endocrine glands are not exocrine, since they secrete into blood. Therefore, merocrine is the best choice as a type of exocrine gland.
