B. `XeO_3`
C. `XeF_6`
D. `XeOF_4`

Answer

To determine which of the given compounds has a square pyramidal structure, we will analyze each option based on their hybridization and molecular geometry.

### Step-by-Step Solution:

1. **Identify the Compounds**: The options provided are:
- Option 1: \( \text{XCF}_4 \)
- Option 2: \( \text{XCO}_3 \)
- Option 3: \( \text{XCF}_6 \)
- Option 4: \( \text{XCOF}_4 \)

2. **Analyze Option 1: \( \text{XCF}_4 \)**:
- **Hybridization**: The central atom (X) in \( \text{XCF}_4 \) has 4 bonding pairs and 2 lone pairs.
- **Hybridization Type**: \( \text{SP}^3\text{D}^2 \).
- **Molecular Geometry**: With 2 lone pairs, the geometry is square planar.

3. **Analyze Option 2: \( \text{XCO}_3 \)**:
- **Hybridization**: The central atom (X) has 3 bonding pairs and 1 lone pair.
- **Hybridization Type**: \( \text{SP}^3 \).
- **Molecular Geometry**: The geometry is trigonal pyramidal.

4. **Analyze Option 3: \( \text{XCF}_6 \)**:
- **Hybridization**: The central atom (X) has 6 bonding pairs and 1 lone pair.
- **Hybridization Type**: \( \text{SP}^3\text{D}^3 \).
- **Molecular Geometry**: The geometry is distorted octahedral.

5. **Analyze Option 4: \( \text{XCOF}_4 \)**:
- **Hybridization**: The central atom (X) has 4 bonding pairs and 1 lone pair.
- **Hybridization Type**: \( \text{SP}^3\text{D}^2 \).
- **Molecular Geometry**: The geometry is square pyramidal.

6. **Conclusion**: The only compound that exhibits a square pyramidal structure is \( \text{XCOF}_4 \).

### Final Answer:
The compound with a square pyramidal structure is **Option 4: \( \text{XCOF}_4 \)**.
