The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Thermite Process**: The thermite process is a method used to produce metals from their oxides through a highly exothermic reaction. This process typically involves the reduction of metal oxides using a more reactive metal. 2. **Identifying the Reducing Agent**: In the thermite process, aluminum is commonly used as the reducing agent. It reacts with metal oxides to reduce them to their elemental form while itself being oxidized to aluminum oxide. 3. **Common Reaction in Thermite Process**: A typical reaction in the thermite process involves iron oxide (Fe2O3) reacting with aluminum (Al). The reaction can be represented as: \[ Fe_2O_3 + 2Al \rightarrow 2Fe + Al_2O_3 \] This shows that aluminum reduces iron oxide to iron. 4. **Conclusion**: Since aluminum is the substance that acts as the reducing agent in the thermite process, the correct answer to the question is aluminum. ### Final Answer: The substance used in the thermite process of reducing metal ores is **Aluminum**. ---
