Select the correct statement.

Options

A. Heterotrophs do not synthesise their own food.
B. Heterotrophs utilise solar energy for photosynthesis.
C. Heterotrophs synthesise their own food.
D. Heterotrophs are capable of converting carbon dioxide and water into carbohydrates.

Explanation

### Step-by-Step Solution:

1. **Understanding Heterotrophs**:
- Heterotrophs are organisms that cannot produce their own food and rely on other organisms for nutrition. They obtain their energy by consuming plants, animals, or organic matter.

2. **Evaluating the Statements**:
- **Statement 1**: "Heterotrophs do not synthesize their own food."
- This statement is correct. Heterotrophs obtain food from other sources rather than producing it themselves.

- **Statement 2**: "Heterotrophs utilize solar energy for photosynthesis."
- This statement is incorrect. Heterotrophs do not perform photosynthesis; that process is characteristic of autotrophs (like plants) that can convert solar energy into chemical energy.

- **Statement 3**: "Heterotrophs synthesize their own food."
- This statement is incorrect. As mentioned earlier, heterotrophs cannot synthesize their own food; they must consume other organisms.

- **Statement 4**: "Heterotrophs are capable of converting carbon dioxide and water into carbohydrates."
- This statement is also incorrect. This process is performed by autotrophs during photosynthesis, not by heterotrophs.

3. **Conclusion**:
- After evaluating all four statements, the only correct statement is: "Heterotrophs do not synthesize their own food."

### Final Answer:
The correct statement is: **Heterotrophs do not synthesize their own food.**
