What do the sebaceous glands secrete?

Sebum

The sebaceous glands are responsible for secreting sebum, which is an oily substance that lubricates and protects the skin and hair follicles. Option B, sweat, is secreted by the sweat glands and helps regulate body temperature by cooling the surface of the skin. Option C, keratin, is a protein that makes up the structure of hair, skin, and nails, but it is not secreted by the sebaceous glands. Option D, melanin, is produced by cells called melanocytes and gives color to the skin, but it is not secreted by the sebaceous glands either.
