Answer

To match the entries of Column I with the appropriate entries of Column II, we will analyze each compound in Column I and determine its corresponding function or characteristic from Column II.

### Step-by-Step Solution:

1. **Identify the first compound: KMnO₄ (Potassium Permanganate)**
- KMnO₄ contains manganese in the +7 oxidation state, which is its highest oxidation state.
- It acts as a strong oxidizing agent because it can reduce its oxidation state by oxidizing another substance.
- **Match:** A → q (used as an oxidizing agent)

2. **Identify the second compound: SnCl₂ (Tin(II) Chloride)**
- In SnCl₂, tin is in the +2 oxidation state. It can lose electrons and be oxidized to Sn⁴⁺.
- Therefore, it acts as a reducing agent because it donates electrons to reduce another substance.
- **Match:** B → r (used as a reducing agent)

3. **Identify the third compound: ZnSO₄ (Zinc Sulfate)**
- ZnSO₄ is commonly used as an electrolyte in electrochemical cells, specifically in the Daniell cell where zinc and copper electrodes are used.
- **Match:** C → s (used as electrolyte in Daniell cell)

4. **Identify the fourth compound: K₂SO₄ (Potassium Sulfate)**
- K₂SO₄ is used in salt bridges, which are essential components in electrochemical cells to maintain electrical neutrality by allowing the flow of ions between the oxidation and reduction half-cells.
- **Match:** D → p (used in salt bridge)

### Final Matches:
- A → q
- B → r
- C → s
- D → p

### Conclusion:
The correct option that matches the entries from Column I to Column II is:
- A → q
- B → r
- C → s
- D → p
