The correct option is C The salivary glands
Exocrine glands are the glands that produce and secrete their secretions through ducts. Salivary gland consists of a large number of acini. Its function is to secrete salivary juice. The juice is conveyed by fine ductules, which unite with similar ductules from other acini to form bigger ductules. The latter unite to form the main duct of the gland. Hence option C is the correct answer.
