Final answer:
Ceruminous glands are responsible for producing earwax, which is distinct from the secretions produced by sweat and sebaceous glands.
Step-by-step explanation:
The glands that produce a secretion commonly called earwax are c) Ceruminous glands. These exocrine glands are specialized structures located in the ear canal. Ceruminous glands are different from other glands such as sweat glands and sebaceous glands. Sweat glands, including eccrine and apocrine glands, release a watery solution that contains salt and metabolic waste for thermoregulation and communication, respectively. Sebaceous glands produce sebum, an oily substance that waterproofs and lubricates the hair and skin. Unlike these, ceruminous glands produce a lipid-rich substance which forms the protective earwax in the external auditory canal.
