Correct Answer: epidermis
Solution : The correct option is the epidermis.
The epidermis of plant roots gives rise to root hairs. Root hairs are microscopic, hair-like structures that grow from the root's epidermal cells in the outermost layer. These small projections increase the surface area of the root and improve the plant's capacity to absorb nutrients and water from the surrounding soil.
