Option 1 -> Incorrectly matches Obsequious with displaying wealth, which confuses it with Ostentatious.
Option 2 -> Incorrectly matches Obsequious with being bossy (Officious trait) and mixes up other definitions.
Option 3 -> Incorrectly matches Obsequious with unpleasant/rude, which is the meaning of Obnoxious.
Option 4 -> Correctly matches: Obsequious (overly eager to please), Obnoxious (unpleasant/rude), Ostentatious (showy display of wealth), Officious (meddlesomely bossy).
Hence, Option 4: (A) - (III), (B) - (I), (C) - (IV), (D) - (II) -> This correctly pairs each word with its proper definition: Obsequious means servile/fawning, Obnoxious means offensive/unpleasant, Ostentatious means vulgar display of wealth, and Officious means interfering/domineering -> correct
