Answer

To solve the problem of matching the reactions in Column I with their corresponding products in Column II, we will analyze each reaction step by step.

### Step 1: Analyze Reaction A
**Reaction:** Cu + dilute HNO₃
**Products:** When copper reacts with dilute nitric acid, it forms copper nitrate (Cu(NO₃)₂), water (H₂O), and nitric oxide (NO).
**Match:** A → P (NO)

### Step 2: Analyze Reaction B
**Reaction:** Cu + concentrated HNO₃
**Products:** When copper reacts with concentrated nitric acid, it forms cupric nitrate (Cu(NO₃)₂), water (H₂O), and nitrogen dioxide (NO₂).
**Match:** B → Q (NO₂)

### Step 3: Analyze Reaction C
**Reaction:** Zn + dilute HNO₃
**Products:** When zinc reacts with dilute nitric acid, it forms zinc nitrate (Zn(NO₃)₂), water (H₂O), and nitrous oxide (N₂O).
**Match:** C → R (N₂O)

### Step 4: Analyze Reaction D
**Reaction:** Zn + concentrated HNO₃
**Products:** When zinc reacts with concentrated nitric acid, it forms zinc nitrate (Zn(NO₃)₂), water (H₂O), and nitrogen dioxide (NO₂).
**Match:** D → S (Zn(NO₃)₂)

### Final Matches:
- A → P (NO)
- B → Q (NO₂)
- C → R (N₂O)
- D → S (Zn(NO₃)₂)

### Summary of Matches:
- A: Cu + dilute HNO₃ → P: NO
- B: Cu + concentrated HNO₃ → Q: NO₂
- C: Zn + dilute HNO₃ → R: N₂O
- D: Zn + concentrated HNO₃ → S: Zn(NO₃)₂
