The correct answer is B, Root hairs.

Epidermal cells of plant roots often develop thin, hair-like extensions called root hairs. These significantly increase the surface area of the root epidermis, maximizing the absorption of water and dissolved mineral nutrients from the soil.

Scales are modified leaves. The endodermis is an inner layer of the root cortex that regulates the movement of water and minerals. Stomata are pores on leaves and stems used for gas exchange.
