Root hair develop in the region of: Meristematic activity, Maturation, Elongation, Root cap

Root has three prominent regions. The region of maturation has dividing meristematic cells. The zone of elongation is responsible for gradual differentiation and maturation. The zone of maturation has very fine thread-like structures known as root hair. These help in the absorption of water and minerals from the soil. So, the correct answer is option B.
