Step 1 — Evaluate Statement I:
 vs :
- In , Sb has oxidation state +5 (higher charge)
- Higher oxidation state → higher charge density → greater polarising power → more covalent character
- Statement I is correct ✓

Step 2 — Evaluate Statement II:
Higher oxides of halogens (e.g.,  vs ):
- Higher oxides are generally less stable than lower ones for halogens
- The stability of halogen oxides decreases with increasing oxidation state
- Statement II is incorrect ✗

Answer: Option (4) — Statement I c
