B. (2) `XeOF_4`
C. (3) `XeO_3`
D. (4) `XeO_4 `

Answer

To solve the question regarding which xenon-OXO compound may not be obtained by hydrolysis of xenon fluorides, we will analyze the hydrolysis reactions of xenon fluorides step by step.

### Step 1: Understand the Hydrolysis of Xenon Fluorides
Xenon fluorides can undergo hydrolysis, which involves their reaction with water to form xenon-OXO compounds and other products. The main xenon fluorides we will consider are XeF2, XeF4, and XeF6.

### Step 2: Hydrolysis of XeF2
When we hydrolyze XeF2, the reaction proceeds as follows:
\[ \text{XeF}_2 + \text{H}_2\text{O} \rightarrow \text{Xe} + 2 \text{HF} + \frac{1}{2} \text{O}_2 \]
- Products: Xenon (Xe), Hydrofluoric acid (HF), and Oxygen (O2).

### Step 3: Hydrolysis of XeF4
When we hydrolyze XeF4, the reaction is:
\[ \text{XeF}_4 + \text{H}_2\text{O} \rightarrow \text{Xe} + 4 \text{HF} + \text{XeO}_3 + \frac{1}{2} \text{O}_2 \]
- Products: Xenon (Xe), Hydrofluoric acid (HF), Xenon trioxide (XeO3), and Oxygen (O2).

### Step 4: Hydrolysis of XeF6
For XeF6, the hydrolysis can yield different products depending on the amount of water used:
1. With limited water:
\[ \text{XeF}_6 + \text{H}_2\text{O} \rightarrow \text{XeF}_4 + 2 \text{HF} \]
2. With more water (2 molecules):
\[ \text{XeF}_6 + 2 \text{H}_2\text{O} \rightarrow \text{XeO}_2\text{F}_2 + 4 \text{HF} \]
3. With even more water (3 molecules):
\[ \text{XeF}_6 + 3 \text{H}_2\text{O} \rightarrow \text{XeO}_3 + 2 \text{HF} \]
- Products: Depending on the reaction conditions, we can obtain Xenon tetrafluoride (XeF4), Xenon dioxydifluoride (XeO2F2), and Xenon trioxide (XeO3).

### Step 5: Identify the Xenon-OXO Compounds
From the hydrolysis reactions analyzed:
- XeO3 can be obtained from XeF4 and XeF6.
- XeO2F2 can be obtained from XeF6.
- XeO4, however, is not produced from any of the hydrolysis reactions of XeF2, XeF4, or XeF6.

### Conclusion
The xenon-OXO compound that may not be obtained by hydrolysis of xenon fluorides is **XeO4**.

### Final Answer
The correct option is **XeO4**.
