Match List \(I\) with List \(II\). Choose the correct answer from the options given below:
| List \(-I\) | List \(-II\) |
| \(A.\) Melting point \([\mathrm{K}]\) | \(I.\) \(\mathrm{Tl}>\mathrm{In}>\mathrm{Ga}>\mathrm{Al}>\mathrm{B}\) |
| \(B.\) Ionic Radius \(\left[\mathrm{M}^{+3} / \mathrm{pm}\right]\) | \(II.\) \(\mathrm{B}>\mathrm{Tl}>\mathrm{Al} \approx \mathrm{Ga}>\mathrm{In}\) |
| \(C.\) \(\Delta_{\mathrm{i}} \mathrm{H}_1 \) \([\mathrm{~kJ} \mathrm{~mol}^{-1}]\) | \(III.\) \(\mathrm{Tl}>\mathrm{In}>\mathrm{Al}>\mathrm{Ga}>\mathrm{B}\) |
| \(D.\) Atomic Radius \([pm]\) | \(IV.\) \(\mathrm{B}>\mathrm{Al}>\mathrm{Tl}>\mathrm{In}>\mathrm{Ga}\) |
- A \(A-III, B-IV, C-I, D-II\)
- B \(A-II, B-III, C-IV, D-I\)
- C \(A-IV, B-I, C-II, D-III\)
