(iii) Edible part of ginger is underground stem.
(iv) Hydrophytes usually possess a well developed root system.

Options

A. (i) and (ii) only
B. (ii) and (iii) only
C. (i),(ii) and (iii)
D. (i),(ii),(iii) and (iv)

Explanation

To solve the question, we need to evaluate each of the provided statements one by one to determine which ones are correct.

### Step-by-Step Solution:

1. **Evaluate Statement (i): "Root caps are present in prop roots."**
- Root caps are protective structures found at the tips of roots, including prop roots. Therefore, this statement is **correct**.

2. **Evaluate Statement (ii): "Pneumatophores help to get oxygen for respiration."**
- Pneumatophores are specialized aerial roots that help plants, especially those in waterlogged conditions, to obtain oxygen from the atmosphere for respiration. Hence, this statement is also **correct**.

3. **Evaluate Statement (iii): "Edible part of ginger is underground stem."**
- The edible part of ginger is indeed the rhizome, which is a type of underground stem. Thus, this statement is **correct**.

4. **Evaluate Statement (iv): "Hydrophytes usually possess a well-developed root system."**
- Hydrophytes are plants that grow in water or wet conditions, and they typically have a poorly developed root system as they do not need to anchor themselves firmly in soil. Therefore, this statement is **incorrect**.

### Conclusion:
After evaluating all the statements:
- Statements (i), (ii), and (iii) are correct.
- Statement (iv) is incorrect.

Thus, the correct option that includes all the correct statements is **1, 2, and 3**.

### Final Answer:
The correct answer is **Option 3: 1, 2, and 3**.
