C. a - iii, b - iv , c - i , d - ii
D. a - iv , b - I , c - ii , d - iii

Answer

To solve the matching question regarding the parts of dicot roots and their respective consistencies, we will go through each part systematically.

### Step-by-Step Solution:

1. **Identify the first part: Epiblema**
- The epiblema is the outermost layer of the root and is characterized by the presence of unicellular root hairs. These root hairs are extensions of the epiblema cells, which help in the absorption of water and nutrients.
- **Match:** Epiblema → Unicellular root hair (i)

2. **Identify the second part: Casparian strips**
- Casparian strips are found in the endodermis of roots and are composed of a waxy substance known as suberin. This waxy material helps in regulating the flow of water and solutes into the vascular system of the plant.
- **Match:** Casparian strips → Waxy material suberin (iii)

3. **Identify the third part: Pericycle**
- The pericycle is a layer of cells located just inside the endodermis and is made up of thick-walled parenchymatous cells. It plays a role in the formation of lateral roots and contributes to the secondary growth of roots.
- **Match:** Pericycle → Thick-walled parenchymatous cells (iv)

4. **Identify the fourth part: Stele**
- The stele refers to the central part of the root, which contains the vascular bundles (xylem and phloem) and pith. It is responsible for the transport of water, nutrients, and food throughout the plant.
- **Match:** Stele → Vascular bundle and pith (ii)

### Final Matches:
- A (Epiblema) → i (Unicellular root hair)
- B (Casparian strips) → iii (Waxy material suberin)
- C (Pericycle) → iv (Thick-walled parenchymatous cells)
- D (Stele) → ii (Vascular bundle and pith)

### Summary of Matches:
- A → i
- B → iii
- C → iv
- D → ii
