Answer

To determine the correct statements regarding antiseptics and disinfectants, let's analyze each statement step by step:

1. **Statement (i)**: "Antiseptics are chemical substances which prevent the growth of microorganisms."
- **Analysis**: This statement is true. Antiseptics are indeed substances that inhibit the growth of microorganisms, making them useful for preventing infections in living tissues.

2. **Statement (ii)**: "Boric acid in dilute aqueous solution is a weak antiseptic for eyes."
- **Analysis**: This statement is also true. Boric acid, when diluted in water, can be used as a mild antiseptic for the eyes, helping to prevent infections.

3. **Statement (iii)**: "0.2 percent solution of phenol is disinfectant."
- **Analysis**: This statement is false. A 0.2% solution of phenol is considered an antiseptic, but it is not strong enough to be classified as a disinfectant. A 1% solution of phenol is typically required to achieve disinfectant properties.

4. **Statement (iv)**: "Iodine is a powerful antiseptic."
- **Analysis**: This statement is true. Iodine is well-known for its antiseptic properties and is commonly used in medical settings to disinfect skin before surgeries.

**Conclusion**: The correct statements are (i), (ii), and (iv).

### Summary of Correct Statements:
