C. If product are two oxy acids one with -ic suffix and otherone with -ous suffix.

Answer

To solve the given reaction \( \text{BF}_3 + \text{H}_2\text{O} \rightarrow \text{H}_3\text{BO}_3 + \text{HBF}_4 \), we will analyze the products formed and determine their classifications.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- Reactants: \( \text{BF}_3 \) (Boron Trifluoride) and \( \text{H}_2\text{O} \) (Water).
- Products: \( \text{H}_3\text{BO}_3 \) (Boric Acid) and \( \text{HBF}_4 \) (Hydrogen Tetrafluoroborate).

2. **Determine the Nature of the Products**:
- **Product 1: \( \text{H}_3\text{BO}_3 \)**:
- This compound contains hydrogen, oxygen, and boron.
- It fits the definition of an oxyacid since it has the formula \( \text{H}_x\text{O}_y\text{X}_z \) where \( X \) is another element (boron in this case).
- The anion formed upon dissociation is \( \text{BO}_3^{3-} \) (borate ion), which corresponds to the suffix "ic" in naming, leading to the name "Boric Acid".

- **Product 2: \( \text{HBF}_4 \)**:
- This compound contains hydrogen, boron, and fluorine but does not contain oxygen.
- Therefore, it does not qualify as an oxyacid.

3. **Classify the Products**:
- We have identified that:
- \( \text{H}_3\text{BO}_3 \) is an oxyacid with the "ic" suffix (Boric Acid).
- \( \text{HBF}_4 \) is not an oxyacid.

4. **Evaluate the Options**:
- Option 1: If the product is an oxyacid with "ic" suffix – **True** (Boric Acid).
- Option 2: If the product is an oxyacid with "ous" suffix – **False** (Only one oxyacid present).
- Option 3: If the products are two oxyacids, one with "ic" and the other with "ous" suffix – **False** (Only one oxyacid present).
- Option 4: If the product is not an oxyacid, neither with "ic" nor with "ous" suffix – **False** (One product is an oxyacid).

5. **Conclusion**:
- The correct classification of the reaction products indicates that the only relevant option is that the product is an oxyacid with the "ic" suffix.

### Final Answer:
The correct option is: **Option 1** - The product is an oxyacid with "ic" suffix (Boric Acid).
