If general formula of oxime and semicarbazone is $\mathrm{C}=\mathrm{N}-\mathrm{Z}$, what is ' $\mathrm{Z}$ ' in oxime (I) semicarbazone (II)?

• A

  $\mathrm{NHCONH}_2 \quad \mathrm{OH}$
• B

  $\mathrm{OH} \quad \mathrm{NH}_2$
• Correct answer
  C

  $\mathrm{OH} \quad \mathrm{NHCONH}_2$
• D

  $\mathrm{NH}_2 \mathrm{OH}$

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