• B. B${}_6$
• C. B${}_7$
• D. K

Answer 1

Answer: (C)

B${}_7$

Vitamin B${}_7$ or Biotin is an important vitamin required for metabolism. It is a water-soluble vitamin which is absorbed from the intestine. Absorption of biotin is prevented when it forms a complex with a protein component called avidin. The biotin-avidin complex is simply excreted out of the body. Raw eggs contain avidin, therefore, consuming them can lead to biotin deficiency.
