C. `{:(A,B,C,D),(3,2,1,5):}`
D. `{:(A,B,C,D),(1,4,4,3):}`

Answer

To solve the matching question, we need to correctly pair the nitrogen compounds from List 1 with their corresponding descriptions in List 2. Let's analyze each compound step by step.

### Step 1: Analyze NO (Nitric Oxide)
- **Characteristics**: NO is a colorless gas and is paramagnetic due to the presence of an unpaired electron.
- **Match**: A) NO → 1) Colourless and paramagnetic

### Step 2: Analyze NO₂ (Nitrogen Dioxide)
- **Characteristics**: NO₂ is a reddish-brown gas and is also paramagnetic.
- **Match**: B) NO₂ → 3) Reddish brown and paramagnetic

### Step 3: Analyze N₂O₃ (Dinitrogen Trioxide)
- **Characteristics**: N₂O₃ is known as the anhydride of nitrous acid (HNO₂). It forms when nitrous acid loses water.
- **Match**: C) N₂O₃ → 5) Anhydride of Nitrous acid

### Step 4: Analyze N₂O₅ (Dinitrogen Pentoxide)
- **Characteristics**: N₂O₅ is known as the anhydride of nitric acid (HNO₃). It forms when nitric acid loses water.
- **Match**: D) N₂O₅ → 4) Anhydride of Nitric acid

### Final Matching Summary:
- A) NO → 1) Colourless and paramagnetic
- B) NO₂ → 3) Reddish brown and paramagnetic
- C) N₂O₃ → 5) Anhydride of Nitrous acid
- D) N₂O₅ → 4) Anhydride of Nitric acid

Thus, the correct matches are:
- A1, B3, C5, D4

### Conclusion:
The correct answer option is the second option which matches the compounds with their respective properties correctly.
