The correct answer to your question is
Sebaceous Glands.
Answer:
A) sebaceous glands
Explanation:
Sebaceous glands are responsible for producing and secreting sebum, a substance that can lubricate and waterproof the skin and hair, giving them a brighter appearance.
However, a high production of sebum through these glands can cause exaggerated greasiness in the hair as well as acne on the skin.
Meanwhile, low sebum production can leave the skin dull and dehydrated, causing premature aging, and leaving hair dry and brittle due to lack of lubrication.
