Match the following
`{:("List - I","List - II"),("A) Trichomes","I) Cambium"),("B) Root hairs","II) Leaves"),("C) Mesophyll","III) Unicellular"),("D) Dicotyledonous","IV) Epidermal hairs stem"):}`

Options

A. `{:(A,B,C,D),(IV,III,II,I):}`
B. `{:(A,B,C,D),(I,II,III,IV):}`
C. `{:(A,B,C,D),(III,IV,II,I):}`
D. `{:(A,B,C,D),(III,IV,I,II):}`

Answer

To solve the matching question, we need to analyze each item in List - I and find the corresponding item in List - II.

### Step-by-Step Solution:

1. **Identify Trichomes (A)**:
- Trichomes are epidermal outgrowths found on the stem of plants. They serve to protect the plant from herbivores and environmental stress.
- **Match**: A) Trichomes → IV) Epidermal hairs stem.

2. **Identify Root Hairs (B)**:
- Root hairs are extensions of the root epidermis and are responsible for water and nutrient absorption. They are unicellular in structure.
- **Match**: B) Root hairs → III) Unicellular.

3. **Identify Mesophyll (C)**:
- Mesophyll is a type of tissue found in the leaves of plants and is primarily involved in photosynthesis.
- **Match**: C) Mesophyll → II) Leaves.

4. **Identify Dicotyledonous (D)**:
- Dicotyledonous plants typically have a cambium layer, which is a layer of actively dividing cells located between the xylem and phloem.
- **Match**: D) Dicotyledonous → I) Cambium.

### Final Matches:
- A → IV
- B → III
- C → II
- D → I

### Conclusion:
The correct option that matches all the items from List - I to List - II is the first option.
