Give appropriate scientific reason for the statement :
Zinc oxide can be reduced to zinc by using carbon monoxide, but aluminium oxide cannot be reduced by a reducing agent.

Explanation

To provide a step-by-step text solution to the question, we can break it down as follows:

### Step 1: Understand the Reduction Process
Reduction is a chemical process where a substance gains electrons or decreases its oxidation state. In metallurgy, reduction is often used to extract metals from their ores.

### Step 2: Identify the Compounds
We are comparing two metal oxides:
- Zinc oxide (ZnO)
