A
A: Found in liver and rice

B
B: Gives strength to the bones

B is vitamin D as it is synthesized by the sunlight. Vitamin D gives strength to the bones.
C represents vitamin A as its deficiency causes poor vision. Vitamin A is not water-soluble. It is a fat-soluble vitamin.
D is required for blood clotting, thus it is vitamin K. Deficiency of vitamin K causes prolonged bleeding.

Rickets

B
Scurvy

C
Pellagra

Refer to the above figure and choose the correct statement regarding A, B and C:

A
C gives less energy as compared to A.

B
B gives more energy than A.

C
A is the quickest source of energy.

D
A special form of A does not provide energy.

Solution

A represents carbohydrates (starch), which yield blue-black colour with iodine solution. Carbohydrates are the quickest source of energy. They get digested faster and provide energy to the cells.
B are proteins as they yield violet color with CuSO₄ and caustic soda. Proteins are body building foods and gives very less energy as compared to A.
C are fats as they leave a grease spot when rubbed on a paper. Fats gives more energy as compared to A i.e. carbohydrates.
