$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{Br} \underset{\Delta}{\stackrel{\mathrm{aq} \cdot \mathrm{KOH}}{\longrightarrow}} \mathrm{A} \underset{\Delta}{\stackrel{\mathrm{KMnO}_{4} / \mathrm{H}^{+}}{\longrightarrow}}$ $\mathrm{B} \underset{\Delta}{\stackrel{\mathrm{NH}_{3}}{\longrightarrow}} \mathrm{C} \underset{\text { alkali }}{\stackrel{\mathrm{Br}_{2}}{\longrightarrow}} \mathrm{D,}$ 'D' is

• A

  $\mathrm{CH}_{3} \mathrm{Br}$
• B

  $\mathrm{CH}_{3} \mathrm{CONH}_{2}$
• Correct answer
  C

  $\mathrm{CH}_{3} \mathrm{NH}_{2}$
• D

  $\mathrm{CHBr}_{3}$

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