Which of the following reactions will give butan-2-one \( \left(\mathrm{CH}_{3} \mathrm{COCH}_{2} \mathrm{CH}_{3}\right) \) as one of the products? A \( \frac{[1] \mathrm{BH}_{3}}{[2] \mathrm{NaOH}, \mathrm{H}_{2} \mathrm{O}_{2}} \) \( \mathrm{B} \) 1) \( \mathrm{O}_{3} \) \( \mathrm{C} \) D 2) \( \mathrm{S}\left(\mathrm{CH}_{3}\right)_{2} \)
