D. `CO_2,N_2,H_2O`

Answer

To solve the question regarding the reaction of Prussic acid (HCN) with oxygen (O2) in the presence of silver (Ag), we will follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Prussic acid (HCN)
- Oxygen (O2)

### Step 2: Understand the Role of Silver (Ag)
Silver (Ag) acts as a catalyst in this reaction. Catalysts are substances that speed up a chemical reaction without being consumed in the process.

### Step 3: Analyze the Reaction
When HCN reacts with O2 in the presence of Ag, it leads to the formation of products. The key points to note are:
- HCN can undergo oxidation.
- The reaction typically leads to the formation of a dimer and water.

### Step 4: Determine the Products
The main products formed from the reaction of HCN with O2 in the presence of Ag are:
- Dimer of cyanide (C2N2)
- Water (H2O)

Additionally, silver oxide (Ag2O) may also be formed as a side product, but the primary products are C2N2 and H2O.

### Step 5: Write the Balanced Equation
The balanced chemical equation for the reaction can be summarized as:
\[ 2 \text{HCN} + \text{O}_2 \xrightarrow{\text{Ag}} \text{C}_2\text{N}_2 + 2 \text{H}_2\text{O} \]

### Final Answer
The products of the reaction of Prussic acid with oxygen in the presence of silver are:
- C2N2 (Dimer of cyanide)
- H2O (Water)
