2. They produce keratin

3. They facilitate hair growth

4. They provide blood supply

The correct answer is: They facilitate hair growth

Hair follicles play a crucial role in the hair growth cycle by facilitating hair growth. Each hair follicle is a small, dynamic organ embedded in the skin that serves as the anchor for hair strands. During the anagen phase, which is the active growth stage of the hair cycle, the hair follicles produce new hair cells that push older ones out of the scalp. This process results in the visible growth of hair. The follicle environment, including cells, the dermal papilla, and surrounding tissue, is essential for the regulation of hair growth, making their role in promoting hair development fundamental. Other options may suggest functions related to the hair or skin, but they do not capture the primary function of hair follicles in the context of hair growth. For example, while follicles help manage oil production and the delivery of nutrients, these do not directly influence the cycle of hair growth as prominently as the growth facilitation aspect does.
