B. (i) & (iv)
C. (ii),(iii) & (iv)
D. (i) & (iii)

Explanation

To solve the question regarding the matches between plant hormones and their precursors, we will analyze each pair provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Auxins and Tryptophan:**
- Auxins are a class of plant hormones that play a crucial role in growth and development.
- They are primarily synthesized from the amino acid **tryptophan**.
- **Conclusion:** The match (i) Auxins - Tryptophan is **correct**.

2. **Understanding Ethylene and Mevalonic Acid:**
- Ethylene is a plant hormone involved in various processes, including fruit ripening.
- Ethylene is synthesized from the amino acid **methionine**, not from mevalonic acid.
- **Conclusion:** The match (ii) Ethylene - Mevalonic Acid is **incorrect**.

3. **Understanding Gibberellins and Methionine:**
- Gibberellins are another class of plant hormones that promote growth and elongation.
- They are synthesized from **mevalonic acid**, not from methionine.
- **Conclusion:** The match (iii) Gibberellins - Methionine is **incorrect**.

4. **Understanding Cytokinins and Aminopurines:**
- Cytokinins are hormones that promote cell division and growth.
- They are derived from **adenine** and its derivatives, which include amino purines.
- **Conclusion:** The match (iv) Cytokinins - Aminopurines is **correct**.

### Final Summary:
- The correct matches are:
- (i) Auxins - Tryptophan (Correct)
- (ii) Ethylene - Mevalonic Acid (Incorrect)
- (iii) Gibberellins - Methionine (Incorrect)
- (iv) Cytokinins - Aminopurines (Correct)

Thus, the correct options are **1 and 4**.

### Answer:
The correct answer is **Option B: 1 and 4**.
