B. `sp^3, sp^3, sp^3d^2`
C. `sp^3, sp^3 d , sp^3 d^2`
D. `sp^3, spd^2, d62 sp^3`

Explanation

To determine the hybridization of the sulfur atom in SF2, SF4, and SF6, we will follow these steps:

### Step 1: Analyze SF2
1. **Count the Valence Electrons**: Sulfur has 6 valence electrons, and each fluorine contributes 1 electron. For SF2, we have:
- 6 (from S) + 2 (from 2 F) = 8 total valence electrons.

2. **Determine Bonds and Lone Pairs**: In SF2, sulfur forms 2 single bonds with fluorine atoms. This uses 2 of the 6 valence electrons, leaving:
- 6 - 2 = 4 electrons, which means there are 2 lone pairs remaining on sulfur.

3. **Calculate the Steric Number**: The steric number is the sum of sigma bonds and lone pairs:
- Steric number = 2 (sigma bonds) + 2 (lone pairs) = 4.

4. **Determine Hybridization**: A steric number of 4 corresponds to sp³ hybridization.

### Step 2: Analyze SF4
1. **Count the Valence Electrons**: For SF4:
- 6 (from S) + 4 (from 4 F) = 10 total valence electrons.

2. **Determine Bonds and Lone Pairs**: In SF4, sulfur forms 4 single bonds with fluorine atoms. This uses 4 of the 6 valence electrons, leaving:
- 6 - 4 = 2 electrons, which means there is 1 lone pair remaining on sulfur.

3. **Calculate the Steric Number**: The steric number is:
- Steric number = 4 (sigma bonds) + 1 (lone pair) = 5.

4. **Determine Hybridization**: A steric number of 5 corresponds to sp³d hybridization.

### Step 3: Analyze SF6
1. **Count the Valence Electrons**: For SF6:
- 6 (from S) + 6 (from 6 F) = 12 total valence electrons.

2. **Determine Bonds and Lone Pairs**: In SF6, sulfur forms 6 single bonds with fluorine atoms. This uses all 6 of the valence electrons, leaving:
- 6 - 6 = 0 electrons, which means there are no lone pairs remaining on sulfur.

3. **Calculate the Steric Number**: The steric number is:
- Steric number = 6 (sigma bonds) + 0 (lone pairs) = 6.

4. **Determine Hybridization**: A steric number of 6 corresponds to sp³d² hybridization.

### Final Answer
- The hybridizations of sulfur in SF2, SF4, and SF6 are:
- SF2: sp³
- SF4: sp³d
- SF6: sp³d²
