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

Answer

To solve the question regarding the reaction of \( \underline{SiH_4} + H_2O \) to form \( H_4SiO_4 + H_2 \), we need to analyze the products formed and determine if they are oxyacids and classify them accordingly.

### Step-by-Step Solution:

1. **Identify the Reactants and Products:**
- Reactants: \( SiH_4 \) (Silane) and \( H_2O \) (Water).
- Products: \( H_4SiO_4 \) (Silicic acid) and \( H_2 \) (Hydrogen gas).

2. **Determine the Nature of the Product \( H_4SiO_4 \):**
- An oxyacid is defined as an acid that contains oxygen, hydrogen, and at least one other element.
- Check the composition of \( H_4SiO_4 \):
- It contains:
- Oxygen (O)
- Hydrogen (H)
- Silicon (Si) as the other element.
- Additionally, it has multiple \( OH \) (hydroxyl) groups, which are indicative of an acid.

3. **Confirm the Structure of \( H_4SiO_4 \):**
- The structure can be represented as:
\[ H_4SiO_4 \rightarrow Si(OH)_4 \]
- This confirms the presence of \( OH \) bonds, which are essential for it to be classified as an oxyacid.

4. **Classify the Oxyacid:**
- The naming convention for oxyacids depends on the number of oxygen atoms and the oxidation state of the central atom.
- \( H_4SiO_4 \) is known as **Silicic acid** or **Orthosilicic acid**.
- The suffix for this oxyacid is **IC**, indicating that it is a higher oxidation state oxyacid.

5. **Examine the Other Product \( H_2 \):**
- \( H_2 \) is simply hydrogen gas and does not contain oxygen or meet the criteria for an oxyacid.
- Therefore, it is not classified as an oxyacid.

6. **Conclusion:**
- The only product that qualifies as an oxyacid is \( H_4SiO_4 \), which is silicic acid with the suffix **IC**.
- The answer to the question is that the product is an oxyacid with the IC suffix.

### Final Answer:
The correct classification is that the product \( H_4SiO_4 \) is an oxyacid with the IC suffix.
