D. For either thermal combination redox reaction or thermal decomposition redox reaction.

Answer

To analyze the given chemical reaction \( \text{CO} + \text{I}_2\text{O}_5(s) \rightarrow \text{CO}_2 + \text{I}_2 \), we will determine the type of reaction it represents.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- Reactants: Carbon monoxide (CO) and iodine pentoxide (I₂O₅).
- Products: Carbon dioxide (CO₂) and iodine (I₂).

2. **Determine the Oxidation States**:
- In CO, carbon has an oxidation state of +2 (since oxygen is -2).
- In I₂O₅, iodine has an oxidation state of +5 (since there are five -2 charges from oxygen).
- In CO₂, carbon has an oxidation state of +4.
- In I₂, iodine has an oxidation state of 0.

3. **Analyze the Changes in Oxidation States**:
- Carbon in CO is oxidized from +2 to +4 in CO₂ (oxidation).
- Iodine in I₂O₅ is reduced from +5 to 0 in I₂ (reduction).

4. **Classify the Reaction**:
- Since one reactant (CO) is oxidized and another reactant (I₂O₅) is reduced, this reaction is a **redox reaction**.
- Specifically, it involves the transfer of electrons between two different molecules, which qualifies it as an **intermolecular redox reaction**.

5. **Consider Other Reaction Types**:
- This reaction does not fit the definition of a disproportionation reaction, where a single compound is transformed into two different oxidation states.
- It is not a simple displacement reaction, as there is no single ion being replaced.
- It is not a thermal combination or decomposition reaction since it does not involve the formation of a single compound from two or the breakdown of a compound.

6. **Conclusion**:
- The correct classification for the reaction \( \text{CO} + \text{I}_2\text{O}_5(s) \rightarrow \text{CO}_2 + \text{I}_2 \) is an **intermolecular redox reaction**.

### Final Answer:
The reaction is classified as an **intermolecular redox reaction**.
