To classify the substances based on the information provided:
- **Substance A** can be broken down by a **physical change**, which suggests it is a **mixture** (as mixtures can be separated physically).
- **Substance B** cannot be broken down by either a **chemical** or **physical change**, indicating it is an **element** (since elements cannot be broken down into simpler substances).
- **Substance C** can only be broken down by a **chemical change**, which means it is a **compound** (as compounds can only be separated into their elements by chemical means).
Based on this reasoning, the correct classification would be:
- Substance A is a **mixture**.
- Substance B is an **element**.
- Substance C is a **compound**.
Thus, the correct response is:
**Substance A is a mixture, substance B is an element, and substance C is a compound.**
- **Substance A** can be broken down by a **physical change**, which suggests it is a **mixture** (as mixtures can be separated physically).
- **Substance B** cannot be broken down by either a **chemical** or **physical change**, indicating it is an **element** (since elements cannot be broken down into simpler substances).
- **Substance C** can only be broken down by a **chemical change**, which means it is a **compound** (as compounds can only be separated into their elements by chemical means).
Based on this reasoning, the correct classification would be:
- Substance A is a **mixture**.
- Substance B is an **element**.
- Substance C is a **compound**.
Thus, the correct response is:
**Substance A is a mixture, substance B is an element, and substance C is a compound.**
