Option 1 -> Incorrectly matches "Denizen" with "Express disapproval of" when it actually means inhabitant.
Option 2 -> Incorrectly matches "Denizen" with "Express disapproval of" and "Depravity" with "Inhabitant."
Option 3 -> Correctly matches: Denizen (inhabitant), Depravity (extreme wickedness), Deprecate (express disapproval), Deride (ridicule).
Option 4 -> Incorrectly matches "Denizen" with "Ridicule" and "Deride" with "Inhabitant."
Hence, Option 3: (A) - (III), (B) - (IV), (C) - (I), (D) - (II) -> This is a vocabulary matching question where understanding etymology helps: "Denizen" refers to a resident/inhabitant, "Depravity" stems from extreme moral corruption, "Deprecate" means to express disapproval (often confused with depreciate), and "Deride" means to mock or ridicule -> correct
