1. (A)-(IV), (B)-(II), (C)-(III), (D)-(I)
2. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
3. (A)-(IV), (B)-(II), (C)-(I), (D)-(III)
4. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Correct answer: (A)-(IV), (B)-(II), (C)-(I), (D)-(III)

Solution

The correct matches are based on the specific reagents required for each reaction type: (A) requires DIBAL-H for selective reduction of esters to aldehydes, (B) uses Zn(Hg) and HCl for Clemmensen reduction of ketones, (C) involves NaBH4 for the reduction of aldehydes to alcohols, and (D) utilizes Grignard reagent followed by water for the formation of alcohols from ketones.
