Identify the product ' $\mathrm{B}$ ' in the following series of reaction. $\mathrm{CH}_3 \mathrm{COOH}+\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH} \underset{\mathrm{H}}{\stackrel{\mathrm{H}^{+}}{\rightleftharpoons}} \mathrm{A} \underset{\mathrm{Ni} / \mathrm{Pd}, \Delta}{\stackrel{\mathrm{H}_2}{\longrightarrow}} \mathrm{B}$

• A

  $\mathrm{CH}_3 \mathrm{OH}$
• Correct answer
  B

  $\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$
• C

  $\mathrm{CH}_3 \mathrm{CH}_2-\mathrm{O}-\mathrm{CH}_3$
• D

  $\mathrm{CH}_3 \mathrm{CH}_2-\mathrm{O}-\mathrm{CH}_2 \mathrm{CH}_3$

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