Option 1 -> Incorrectly matches Soliloquy with "short novel" and Elegy with "form of letters".
Option 2 -> Correctly matches all literary terms: Soliloquy (stage speech), Epistolary (letters), Elegy (sad poem/song), Novelette (short novel).
Option 3 -> Incorrectly matches Soliloquy with "form of letters" and Novelette with "stage speech".
Option 4 -> Incorrectly matches Soliloquy with "sad poem" and contains an error (C repeated as I).
Hence, Option 2: (A) - (III), (B) - (IV), (C) - (I), (D) - (II) -> This correctly pairs Soliloquy with the theatrical monologue definition, Epistolary with letter-form writing, Elegy with the mourning poem/song, and Novelette with the short novel description -> correct
