Options

A. Cu
B. S
C. C
D. Zn

Explanation

To solve the question regarding which element is oxidized by hot concentrated \( H_2SO_4 \) into two gaseous products, we will analyze each option provided.

### Step-by-step Solution:

1. **Understanding the Reaction**:
Hot concentrated \( H_2SO_4 \) acts as a moderately strong oxidizing agent. It can oxidize both metals and non-metals, leading to the formation of various products, including gases.

2. **Analyzing Each Option**:
- **Option 1: Copper (Cu)**:
- Reaction: \( Cu + 2H_2SO_4 \rightarrow CuSO_4 + SO_2 + 2H_2O \)
- Products: \( CuSO_4 \) (solid), \( SO_2 \) (gas), \( H_2O \) (liquid)
- Gaseous Products: 1 (SO2)

- **Option 2: Sulfur (S)**:
- Reaction: \( S + 2H_2SO_4 \rightarrow 3O_2 + 2H_2O \)
- Products: \( SO_2 \) (gas), \( H_2O \) (liquid)
- Gaseous Products: 1 (SO2)

- **Option 3: Carbon (C)**:
- Reaction: \( C + 2H_2SO_4 \rightarrow CO_2 + SO_2 + 2H_2O \)
- Products: \( CO_2 \) (gas), \( SO_2 \) (gas), \( H_2O \) (liquid)
- Gaseous Products: 2 (CO2 and SO2)

- **Option 4: Zinc (Zn)**:
- Reaction: \( Zn + H_2SO_4 \rightarrow ZnSO_4 + SO_2 + 2H_2O \)
- Products: \( ZnSO_4 \) (solid), \( SO_2 \) (gas), \( H_2O \) (liquid)
- Gaseous Products: 1 (SO2)

3. **Conclusion**:
From the analysis, the only element that is oxidized by concentrated \( H_2SO_4 \) into two gaseous products is **Carbon (C)**, producing \( CO_2 \) and \( SO_2 \).

### Final Answer:
The element that is oxidized by hot concentrated \( H_2SO_4 \) into two gaseous products is **Carbon (C)**.
