Options

A. `a-iii, b-i,c-v, d-ii`
B. `a-ii, b-v, c-iv, d-iii`
C. `a-ii, b-i, c-v, d-iv`
D. `a-iv, b-iii, c-ii,d-i`

Answer

To solve the question of matching the lists of plant growth regulators with their respective functions and chemical nature, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Functions in Column I:**
- (a) Early seed production in conifers
- (b) Seed development maturation
- (c) Lateral shoot growth
- (d) Root hair formation

2. **Identify the Chemical Nature in Column II:**
- (i) Indole substance
- (ii) Terpene substance
- (iii) Volatile substance
- (iv) Adenine derivative
- (v) Carotenoid derivative

3. **Match Each Function with the Correct Plant Growth Regulator:**
- **(a) Early seed production in conifers:**
- This is promoted by **Gibberellin**, which is a **terpene substance**.
- Match: (a) → (ii)

- **(b) Seed development maturation:**
- This is influenced by **Abscisic Acid**, which is a **carotenoid derivative**.
- Match: (b) → (v)

- **(c) Lateral shoot growth:**
- This is stimulated by **Cytokinin**, which is an **adenine derivative**.
- Match: (c) → (iv)

- **(d) Root hair formation:**
- This is regulated by **Ethylene**, which is a **volatile substance**.
- Match: (d) → (iii)

4. **Compile the Matches:**
- (a) → (ii) (Gibberellin → Terpene substance)
- (b) → (v) (Abscisic Acid → Carotenoid derivative)
- (c) → (iv) (Cytokinin → Adenine derivative)
- (d) → (iii) (Ethylene → Volatile substance)

5. **Final Matching:**
- A: (ii)
- B: (v)
- C: (iv)
- D: (iii)

### Conclusion:
The correct matches are:
- (a) → (ii)
- (b) → (v)
- (c) → (iv)
- (d) → (iii)
