Option 1 → (A)-(II), (B)-(III), (C)-(IV), (D)-(I) - Correctly matches convalescence with recovery period, euphoria with temporary happiness, verisimilitude with appearing true, and oblivion with being forgotten.
Option 2 → (A)-(II), (B)-(IV), (C)-(I), (D)-(III) - Incorrectly matches euphoria with "appearing true" and oblivion with "happiness."
Option 3 → (A)-(III), (B)-(II), (C)-(IV), (D)-(I) - Incorrectly swaps convalescence and euphoria definitions.
Option 4 → (A)-(I), (B)-(II), (C)-(IV), (D)-(III) - Incorrectly matches convalescence with "being forgotten" and euphoria with "recovery period."
Hence, Option 1: (A)-(II), (B)-(III), (C)-(IV), (D)-(I) → Convalescence specifically refers to the recovery period after illness/surgery, euphoria describes intense but temporary happiness, verisimilitude means having the appearance of truth or reality, and oblivion refers to the state of being forgotten → correct
