Question

Match the vitamins given in column I with the deficiency disease caused by it given in column II and mark the appropriate choice.

Column I	Column II
Vitamin ${{\text{B}}_{\text{1}}}$	Convulsions
Vitamin ${{\text{B}}_2}$	Pernicious anaemia
Vitamin ${{\text{B}}_{{\text{12}}}}$	Beriberi
Vitamin ${{\text{B}}_6}$	Cheilosis

A. (A)-(iv), (B)-(iii), (C)-(i), (D)-(ii)
B. (A)-(i), (B)-(iv), (C)-(iii), (D)-(ii
C. (A)-(ii), (B)-(i), (C)-(iv), (D)-(iii)
D. (A)-(iii), (B)-(iv), (C)-(ii), (D)-(i)

Answer 1

The organic substances that are supplied to the human body to allow a proportionate growth or to maintain the structure are known as vitamins. The deficiency of various vitamins can lead to different diseases.

Complete step by step answer: The deficiency of vitamin ${{\text{B}}_{\text{1}}}$ causes a disease called Beriberi.
The deficiency of vitamin ${{\text{B}}_2}$ causes cheilosis which retards the growth and digestion.
The deficiency of vitamin ${{\text{B}}_{12}}$ causes pernicious anaemia.
The deficiency of vitamin ${{\text{B}}_6}$ causes convulsions.
Thus, the correct matching order is (A)-(iii), (B)-(iv), (C)-(ii), (D)-(i).
So, the correct answer is “Option D”.

Additional Information: Vitamin ${{\text{B}}_{\text{1}}}$ is also known as thiamine. The sources of vitamin ${{\text{B}}_{\text{1}}}$ are rice, wheat, meat and green vegetables.
Vitamin ${{\text{B}}_2}$ is also known as riboflavin. The sources of vitamin ${{\text{B}}_2}$ are egg yolk, fish and yeast. Other diseases caused due to the deficiency of vitamin ${{\text{B}}_2}$ are inflammation of tongue, drying of lips at corners of mouth.
The sources of vitamin ${{\text{B}}_{12}}$ are egg, curd, fish, pig liver, and sheep. Other diseases caused due to the deficiency of vitamin ${{\text{B}}_{12}}$ are degradation of spinal cord.
Vitamin ${{\text{B}}_6}$ is a mixture of pyridoxine, pyridoxal and pyridoxamine. The sources of vitamin ${{\text{B}}_6}$ are wheat, fish, maize, milk, cereals, and yeast. Other diseases caused due to the deficiency of vitamin ${{\text{B}}_6}$ are failure to gain weight, mental changes, derangement of enzymes that control metabolism of carbohydrates.

Note: All the vitamins ${{\text{B}}_{\text{1}}}$, ${{\text{B}}_2}$, ${{\text{B}}_{12}}$ and ${{\text{B}}_6}$ are water soluble vitamins. Being water soluble these are readily excreted through urine. These vitamins are not toxic to the human body. They cannot be stored in the body.
Structures of all the vitamins ${{\text{B}}_{\text{1}}}$, ${{\text{B}}_2}$, ${{\text{B}}_{12}}$ and ${{\text{B}}_6}$ contain rings that contain hetero atoms. Thus, they have heterocyclic structures.
