B. `Si(OH)_(2)F_(2)`
C. `H_(2)SiF_(6)`
D. `Si(OH)_(4)`

Explanation

To solve the question regarding the hydrolysis of silicon tetrafluoride (SiF₄), we can break down the process step by step.

### Step-by-Step Solution:

1. **Understanding Hydrolysis**: Hydrolysis is a chemical reaction involving water, where a compound reacts with water to form new products. In this case, we are looking at the hydrolysis of silicon tetrafluoride (SiF₄).

2. **Chemical Reaction**: The reaction can be represented as:
\[ \text{SiF}_4 + 4 \text{H}_2\text{O} \rightarrow \text{Si(OH)}_4 + 4 \text{HF} \]
Here, SiF₄ reacts with water (H₂O).

3. **Formation of Products**: During hydrolysis, silicon tetrafluoride (SiF₄) reacts with water to form silicic acid (Si(OH)₄) and hydrofluoric acid (HF).

4. **Identifying the Products**: The products of the hydrolysis are:
- Silicic acid: Si(OH)₄
- Hydrofluoric acid: HF

5. **Final Answer**: Therefore, upon hydrolysis, SiF₄ gives:
\[ \text{Si(OH)}_4 \text{ and } \text{HF} \]
