Solution

The correct option is A I, II and III
According to Fajan's rule, polarisability increases with the increase in negative charge and the size of the anion.
The charge on S2 is higher than that on Cl and smaller than that onP3. Also, the size of S2 is smaller than Se2. Hence, the polarisability of S2 is higher than Cl but smaller than P3 and Se2.
S2 has a larger size than O2, so the former has more polarisability.
