AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for a type of substance that cannot be broken down into simpler substances. 2. **Identifying Types of Substances**: There are two main types of substances in chemistry: elements and compounds. - **Elements**: These are pure substances that consist of only one type of atom. - **Compounds**: These are substances formed when two or more different types of atoms chemically bond together. 3. **Analyzing Elements**: Elements cannot be broken down into simpler substances. They are the most basic form of matter. - Examples of elements include metals like iron and gold, and non-metals like oxygen and carbon. 4. **Analyzing Compounds**: Compounds can be broken down into simpler substances (elements) through chemical reactions. For example, water (H2O) can be broken down into hydrogen and oxygen. 5. **Conclusion**: Since elements are the only substances that cannot be broken down into simpler substances, the answer to the question is "elements". **Final Answer**: Elements cannot be broken down into simpler substances. ---
