D. Oxidising agent

Answer

To solve the question regarding the reaction of copper oxide (CuO) with sulfuric acid (H₂SO₄), we need to analyze the reaction step by step.

### Step 1: Identify the Reaction
The reaction given is:
\[ \text{CuO} + \text{H}_2\text{SO}_4 \rightarrow \text{CuSO}_4 + \text{H}_2\text{O} \]

### Step 2: Understand the Reactants
- **CuO (Copper Oxide)**: This is a basic oxide.
- **H₂SO₄ (Sulfuric Acid)**: This is a strong acid.

### Step 3: Identify the Type of Reaction
This reaction can be classified as a **neutralization reaction**, where an acid reacts with a base to produce a salt and water.

### Step 4: Determine the Products
The products of the reaction are:
- **CuSO₄ (Copper Sulfate)**: This is a salt.
- **H₂O (Water)**: This is produced as a byproduct.

### Step 5: Identify the Property of H₂SO₄
In this reaction, sulfuric acid (H₂SO₄) is acting as an acid. The property of H₂SO₄ that is responsible for this reaction is its ability to donate protons (H⁺ ions) to the basic oxide (CuO).

### Conclusion
The property of sulfuric acid that is responsible for the reaction with copper oxide is its **acidic property**.

### Final Answer
The property responsible for the reaction \( \text{CuO} + \text{H}_2\text{SO}_4 \rightarrow \text{CuSO}_4 + \text{H}_2\text{O} \) is the **acidic property** of H₂SO₄.
