To determine which statement about adrenalin is correct, let's analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Adrenalin**:
- Adrenalin, also known as epinephrine, is a hormone produced by the adrenal glands. It plays a crucial role in the body's fight-or-flight response.

2. **Evaluating the Options**:
- **Option 1**: "It regulates the level of sugar in the blood."
- This statement is incorrect. The hormone responsible for regulating blood sugar levels is glucagon, which is secreted by the pancreas, not adrenalin.

- This statement is incorrect. The hormones that control breast development in females are estrogen and progesterone, not adrenalin.

- **Option 4**: "It controls the development of facial hair in males."
- This statement is also incorrect. The hormone responsible for the development of facial hair in males is testosterone, not adrenalin.

3. **Conclusion**:
- After evaluating all the options, the correct statement about adrenalin is: **"It maintains the balance of salt in the body."**
