The catenation tendency of $\mathrm{C}, \mathrm{Si}$ and $\mathrm{Ge}$ is in the order $\mathrm{Ge} < \mathrm{Si} < \mathrm{C}$. The bond energies (in $\mathrm{kJ} \mathrm{mol}^{-1}$ ) of $\mathrm{C}-\mathrm{C}, \mathrm{Si}-\mathrm{Si}$ and $\mathrm{Ge}-\mathrm{Ge}$ bonds, respectively are

• Correct answer
  A

  $167,180,348$
• B

  $180,167,348$
• C

  $348,167,180$
• D

  $348,180,167$

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