Merocrine are exocrine glands that have vesicles that help in the secretion of the secretory fluid via the process of the exocytosis from the cells that secrets into the ducts and ultimately on the surface of the lumen.
Holocrine in other hand is the glands which produce the oil like secretory fluid from the various type of cells in their cytoplasm and released due to ruptured of the plasma membrane.
Thus, the correct answer is - merocrine, and holocrine.
Merocrine glands are the kind of exocrine glands that secretes substance on the surface of epithelial via duct. The exocrine glands are salivary, mucous, and mammary glands.
