The ultimate product of oxidation of most of hydrogen and carbon in foodstuffs are

Options

A. `H_(2)O` alone
B. `CO_(2)` alone
C. `H_(2)O` and `CO_(2)`
D. None of these

Explanation

To solve the question regarding the ultimate products of oxidation of hydrogen and carbon in foodstuffs, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of Foodstuffs**:
- Foodstuffs primarily consist of carbohydrates, fats, and proteins, which are made up of carbon (C), hydrogen (H), and oxygen (O).

2. **Understand the Oxidation Process**:
- Oxidation is a chemical reaction where substances combine with oxygen. In the case of foodstuffs, the carbon and hydrogen present will react with oxygen (O2) during metabolism.

3. **Write the General Reaction**:
- When carbon and hydrogen are oxidized, the general reaction can be represented as:
\[ \text{C} + \text{O}_2 \rightarrow \text{CO}_2 \]
\[ \text{H}_2 + \text{O}_2 \rightarrow \text{H}_2\text{O} \]

4. **Determine the Ultimate Products**:
- The complete oxidation of carbon results in carbon dioxide (CO2), and the complete oxidation of hydrogen results in water (H2O). Therefore, when foodstuffs are oxidized, the ultimate products are:
\[ \text{CO}_2 \text{ (carbon dioxide)} \text{ and } \text{H}_2\text{O} \text{ (water)} \]

5. **Conclusion**:
- The ultimate products of the oxidation of most of the hydrogen and carbon in foodstuffs are carbon dioxide (CO2) and water (H2O).

### Final Answer:
The ultimate product of oxidation of most of hydrogen and carbon in foodstuffs is **CO2 and H2O**.
