Explanation

### Step-by-Step Solution

1. **Understanding the Question**: The question asks about the functions of the hormone adrenaline and provides four options regarding its role in the body.

2. **Analyzing Option A**: The first option states that adrenaline helps the body adjust stress levels when one is very angry or worried. This is accurate because adrenaline, also known as epinephrine, is released during stressful situations and is often referred to as the "fight or flight" hormone. It prepares the body to respond to perceived threats.

3. **Analyzing Option B**: The second option claims that adrenaline helps to control height. This is incorrect. The hormone responsible for regulating growth and height is the growth hormone, not adrenaline.

4. **Analyzing Option C**: The third option suggests that adrenaline helps to control the balance of electrolytes in the body. This is also incorrect. The hormone that plays a significant role in regulating electrolyte balance is aldosterone.

5. **Analyzing Option D**: The fourth option states that adrenaline helps control the level of sugar in the blood. While adrenaline does have some effect on glucose metabolism, the primary hormones responsible for regulating blood sugar levels are insulin and glucagon.

6. **Conclusion**: After analyzing all the options, it is clear that option A is the correct answer. Adrenaline helps the body adjust stress levels when one is very angry or worried.

### Final Answer
**The correct answer is option A: Adrenaline helps the body to adjust stress levels when one is very angry or worried.**
