(A) "How like a winter hath my absence been from thee." → Uses "like" to compare absence to winter → Simile (IV)
(B) "The rain poured down the wedding guests, indifferent to their plans." → Rain is given the human quality of being "indifferent" → Personification (III)
(C) "Crooks conspire with the crooked king." → Repetition of the "cr" sound at the beginning of consecutive words → Alliteration (I)
(D) "But soft what light through yonder window breaks. It is east and Juliet is the sun." → Direct comparison stating "Juliet is the sun" without using "like" or "as" → Metaphor (II)
Hence, Option 3: (A) - (IV), (B) - (III), (C) - (I), (D) - (II) → This correctly matches simile with the "like" comparison, personification with human qualities given to rain, alliteration with consonant sound repetition, and metaphor with the direct comparison of Juliet to the sun → correct
