Explanation

To solve the question regarding the behavior of sulfuric acid (H₂SO₄) as an acid, oxidizing agent, and dehydrating agent, we will analyze each of the provided equations step by step.

### Step-by-Step Solution:

1. **Identify the Reactions**: We have four reactions to analyze:
- (a) \( 5H_2SO_4(\text{conc}) + 4Zn \rightarrow 4Zn^{2+} + H_2S + 4SO_4^{2-} + 4H_2O \)
- (b) \( H_2SO_4(\text{dil}) + Zn \rightarrow Zn^{2+} + H_2 + SO_4^{2-} \)
- (c) \( C_6H_{12}O_6 \xrightarrow{H_2SO_4(\text{conc})} 6C + 6H_2O \)
