Option 1 -> Incorrectly matches Alliteration with irony's definition and misaligns other terms.
Option 2 -> Incorrectly matches Alliteration with sound imitation and Onomatopoeia with consonant repetition.
Option 3 -> Correctly matches all figures of speech: Alliteration with consonant repetition (III), Onomatopoeia with sound imitation (IV), Oxymoron with contradictory words (I), and Irony with contrast between said and meant (II).
Option 4 -> Incorrectly matches Alliteration with contradictory words and Irony with sound imitation.
Hence, Option 3: (A) - (III), (B) - (IV), (C) - (I), (D) - (II) -> Alliteration is the repetition of initial consonant sounds (e.g., "Peter Piper"), Onomatopoeia uses words mimicking sounds (e.g., "buzz", "hiss"), Oxymoron combines contradictions (e.g., "deafening silence"), and Irony involves saying one thing while meaning another -> correct
