B. the product is oxy acid with -ous suffix
C. the product are two oxy acids one with -ic suffix and otherone with -ous suffix.
D. the product is not oxy acid, neither with -ic suffix nor with -ous suffix

Answer

To solve the reaction \( \text{SiF}_4 + \text{H}_2\text{O} \rightarrow \text{H}_4\text{SiO}_4 + \text{HF} \), we will analyze the reactants and products step by step.

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Silicon tetrafluoride (\( \text{SiF}_4 \))
- Water (\( \text{H}_2\text{O} \))

### Step 2: Identify the Products
The products of the reaction are:
- Tetrahydroxysilicate (\( \text{H}_4\text{SiO}_4 \)), which is an oxoacid of silicon.
- Hydrogen fluoride (\( \text{HF} \))

### Step 3: Classify the Product
The product \( \text{H}_4\text{SiO}_4 \) is known as silicic acid or orthosilicic acid. This is an oxoacid because it contains oxygen, hydrogen, and another element (silicon).

### Step 4: Determine the Naming Convention
Oxoacids are typically named based on the number of oxygen atoms and the central atom. In this case:
- The presence of silicon and the structure of \( \text{H}_4\text{SiO}_4 \) indicates that it is an oxoacid with the "ic" suffix, which is used for acids derived from an anion with more oxygen atoms.

### Step 5: Conclusion
Based on the analysis, the correct option regarding the product is that it is an oxyacid with the "ic" suffix.

### Final Answer
The product \( \text{H}_4\text{SiO}_4 \) is an oxoacid with the "ic" suffix, specifically known as silicic acid.
