Options

A. displacement reaction
B. double displacement reaction
C. combination reaction
D. decomposition reaction

Explanation

To determine the type of reaction that occurs when carbon dioxide reacts with carbon to form carbon monoxide, we can analyze the reaction step by step.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactants are carbon dioxide (CO₂) and carbon (C).
- The product formed is carbon monoxide (CO).

2. **Write the Reaction**:
- The chemical equation for the reaction can be written as:
\[ \text{CO}_2 + \text{C} \rightarrow \text{CO} \]

3. **Classify the Reaction**:
- We need to determine what type of reaction this is. The options are:
- Displacement Reaction
- Double Displacement Reaction
- Combination Reaction
- Decomposition Reaction

4. **Analyze Each Reaction Type**:
- **Displacement Reaction**: Involves one element displacing another in a compound. Here, there is no displacement of elements; hence, it is not a displacement reaction.
- **Double Displacement Reaction**: Involves two compounds exchanging components. This does not apply here as we are not dealing with two compounds exchanging parts.
- **Combination Reaction**: Involves two or more reactants combining to form a single product. In this case, carbon dioxide and carbon combine to form carbon monoxide, which fits the definition of a combination reaction.
- **Decomposition Reaction**: Involves a single compound breaking down into two or more simpler substances. This does not apply as there is no breakdown of a compound.

5. **Conclusion**:
- Since the reaction involves the combination of carbon dioxide and carbon to form carbon monoxide, it is classified as a **combination reaction**.

### Final Answer:
The reaction of carbon dioxide with carbon to form carbon monoxide is an example of a **combination reaction**.
