Answer

To solve the problem of matching the properties of halogens with their respective orders, we will analyze each property one by one and determine the correct matches.

### Step 1: Analyze Melting Points (M.Pts)
- **Observation**: As we move down the group of halogens (F, Cl, Br, I), the state of matter changes from gas (F and Cl) to liquid (Br) to solid (I).
- **Conclusion**: The melting point increases down the group. Thus, the order is:
- I₂ > Br₂ > Cl₂ > F₂
- **Match**: (A) M.Pts corresponds to (1) I₂ > Br₂ > Cl₂ > F₂.

### Step 2: Analyze Boiling Points (B.Pts)
- **Observation**: Similar to melting points, the boiling points also increase down the group due to stronger intermolecular forces in larger atoms.
- **Conclusion**: The order is:
- I₂ > Br₂ > Cl₂ > F₂
- **Match**: (B) B.Pts corresponds to (2) I₂ > Br₂ > Cl₂ > F₂.

### Step 3: Analyze Electron Affinity
- **Observation**: Electron affinity generally increases with decreasing atomic size. However, fluorine, being the smallest, has a high electron-electron repulsion which lowers its electron affinity compared to chlorine.
- **Conclusion**: The order is:
- Cl > F > Br > I
- **Match**: (C) Electron affinity corresponds to (2) Cl > F > Br > I.

### Step 4: Analyze Bond Dissociation Energy
- **Observation**: Bond dissociation energy is influenced by bond length. Larger atoms have longer bonds and thus lower bond dissociation energy. Fluorine has high electron-electron repulsion due to its small size.
- **Conclusion**: The order is:
- F₂ > Cl₂ > Br₂ > I₂
- **Match**: (D) Bond dissociation energy corresponds to (3) F₂ > Cl₂ > Br₂ > I₂.

### Final Matches
- (A) M.Pts corresponds to (1) I₂ > Br₂ > Cl₂ > F₂
- (B) B.Pts corresponds to (2) I₂ > Br₂ > Cl₂ > F₂
- (C) Electron affinity corresponds to (2) Cl > F > Br > I
- (D) Bond dissociation energy corresponds to (3) F₂ > Cl₂ > Br₂ > I₂

### Correct Match Summary
- A → 1
- B → 2
- C → 2
- D → 3
