**Chemical Reaction Analysis: Identifying the Reducing Agent**

In the following chemical reaction, identify the reducing agent:

\[ \frac{5}{8} \text{S}_8(s) + 6 \text{KNO}_3(aq) + 2 \text{CaCO}_3(s) \rightarrow 3 \text{K}_2\text{SO}_4(aq) + 2 \text{CaSO}_4(s) + \text{CO}_2(g) + 3 \text{N}_2(g) \]

**Options:**
- **A.** CaCO₃
- **B.** KNO₃
- **C.** CO₂
- **D.** N₂
- **E.** S₈

**Explanation:**
This problem involves identifying the reducing agent in a chemical reaction. The reducing agent is the substance that donates electrons to another substance, thereby reducing it. In return, the reducing agent is oxidized.

To solve this, you need to determine which substance undergoes oxidation, as this will be the reducing agent. By analyzing the equation, observe the change in oxidation states of the involved elements, especially sulfur and nitrogen, to find which element is oxidized.
