Which one of the following is not a surfactant?

• A

  
  
• Correct answer
  B

  \(\mathrm{CH}_3-\left(\mathrm{CH}_2\right)_{14}-\mathrm{CH}_2-\mathrm{NH}_2\)
• C

  \(\mathrm{CH}_3-\left(\mathrm{CH}_2\right)_{16}-\mathrm{CH}_2 \mathrm{OSO}_2^{-} \mathrm{Na}^{+}\)
• D

  \(\mathrm{OHC}-\left(\mathrm{CH}_2\right)_{14}-\mathrm{CH}_2-\mathrm{COO}^{-} \mathrm{Na}^{+}\).

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