Answer

To solve the question of matching elements from Column I with their corresponding periodic properties in Column II, we can follow these steps:

### Step 1: Analyze the First Element - Fluorine (F)
- **Property to Match**: Maximum ionization energy
- **Reasoning**: Fluorine is the most electronegative element and is located at the top of Group 17 (halogens). It has the highest electronegativity and is known for its high ionization energy.
- **Match**: A (F) → Q (Maximum electronegativity)

### Step 2: Analyze the Second Element - Chlorine (Cl)
- **Property to Match**: Maximum electron affinity
- **Reasoning**: Chlorine is also a halogen, located below fluorine in Group 17. Chlorine has a high tendency to gain an electron, which gives it the maximum electron affinity among the elements.
- **Match**: B (Cl) → R (Maximum electron affinity)

### Step 3: Analyze the Third Element - Iron (Fe)
- **Property to Match**: Variable oxidation state
- **Reasoning**: Iron is a transition metal known for exhibiting multiple oxidation states, primarily +2 and +3. This characteristic is typical of transition metals.
- **Match**: C (Fe) → S (Variable oxidation state)

### Step 4: Analyze the Fourth Element - Helium (He)
- **Property to Match**: Maximum ionization energy
- **Reasoning**: Helium is a noble gas and has the highest ionization energy among all elements due to its complete electron shell configuration. It is located at the top of Group 18.
- **Match**: D (He) → P (Maximum ionization energy)

### Final Matches:
- A → Q (Fluorine - Maximum electronegativity)
- B → R (Chlorine - Maximum electron affinity)
- C → S (Iron - Variable oxidation state)
- D → P (Helium - Maximum ionization energy)

### Conclusion:
The correct matches are:
- A to Q
- B to R
- C to S
- D to P

Thus, the best option is **C**.
