Final answer:
Sweat glands are correctly called eccrine glands, which are responsible for temperature regulation by releasing mostly water through pores on the skin surface. The correct option is 3) Eccrine glands
Step-by-step explanation:
Sweat glands are more correctly called eccrine glands. These are coiled glands in the dermis that release sweat, which is mostly water, to the surface of the skin through tiny openings called pores.
This process is crucial for temperature regulation. While apocrine glands are also sweat glands, they are found in specific areas like armpits and groin and do not play a primary role in cooling the body.
Other glands like sebaceous glands and ceruminous glands secrete oils and earwax, respectively, and are not primarily responsible for sweat production. The correct option is 3) Eccrine gland.
