Identify the suitable reagent for the following conversion

• A

  (i) $\mathrm{LiAlH}_4$, (ii) $\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}$
• Correct answer
  B

  (i) $\mathrm{AlH}(\mathrm{iBu})_2$ (ii) $\mathrm{H}_2 \mathrm{O}$
• C

  (i) $\mathrm{NaBH}_4$, (ii) $\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}$
• D

  $\mathrm{H}_2 / \mathrm{Pd}-\mathrm{BaSO}_4$

Hence, the correct answer is option: 'B'.
