D. `H_(3)PO_(5)`

Answer

To determine the phosphorus-containing compound produced in the reaction of nitric acid (HNO₃) with phosphorus pentoxide (P₄O₁₀), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
The reactants in this reaction are nitric acid (HNO₃) and phosphorus pentoxide (P₄O₁₀).

2. **Understand the Reaction**:
When HNO₃ reacts with P₄O₁₀, it typically leads to the formation of nitrogen oxides and phosphorus-containing acids.

3. **Determine the Products**:
The products of this reaction are dinitrogen pentoxide (N₂O₅) and metaphosphoric acid (HPO₃).

4. **Balancing the Reaction**:
The balanced chemical equation can be represented as:
\[ 4 HNO₃ + P₄O₁₀ \rightarrow 2 N₂O₅ + 4 HPO₃ \]
This shows that for every 4 moles of nitric acid, we produce 2 moles of dinitrogen pentoxide and 4 moles of metaphosphoric acid.

5. **Identify the Phosphorus Compound**:
From the balanced equation, we see that the phosphorus-containing compound produced is metaphosphoric acid, which has the formula HPO₃.

6. **Conclusion**:
Therefore, the phosphorus-containing compound produced in the reaction of HNO₃ with P₄O₁₀ is HPO₃.

### Final Answer:
The correct option is **HPO₃**.
