A. Thiamin
B. Riboflavin
C. Niacin
D. Pantothenic acid

Answer 1

Hint: Vitamin G is required by the body to perform cellular respiration. Eggs, meat, green vegetables, milk, and mushroom are rich in vitamin G. It can be used in the treatment of migraines. It is one of the B complex vitamins. It is water-soluble vitamin but less soluble than other B vitamins.

Complete answer: Vitamins are essential micronutrients required by the body for several cellular level metabolic reactions. Vitamins act as cofactors for various enzymes. These are also involved in cellular respiration and division. Several vitamins are acquired from diet and each one is required in a particular percentage to sustain normal body functioning. Vitamin G or Riboflavin is one of the B complex vitamins commonly called B2, is an essential vitamin taken through food and dietary supplements. It is present in mushrooms, meat, eggs, green vegetables, and dairy products. It is used to prevent riboflavin deficiency and is an important component of cellular respiration. Recently it has been studied to show effects in treating migraines. Riboflavin is also effectively used as a cure in corneal ectasia which is characterized by thinning of the cornea. Riboflavin is excessively removed from the body through urination as it is water-soluble. There is no toxicity effect of excess riboflavin in the body as it gets removed regularly. Riboflavin or Vitamin G is an essential vitamin for skin and oral mucosa health. It forms an essential component of coenzymes like FMD and FAD which plays an important role in the electron transport chain of cellular respiration. Thus, it needs to be taken in stable amounts. The normal estimated average requirement set by the National Academy of Medicine for riboflavin is $0.9$ mg/day for women and $1.1$ mg/day for men.
Hence, option B is the correct answer.

Note: In animals, riboflavin deficiency may lead to a lack of growth and development. Growth failure, ataxia, weakness, and inability to stand are some of the symptoms observed in dogs who lack riboflavin. Hair loss, corneal opacity, fatty degeneration of the kidney is observed in humans who show a severe deficiency of riboflavin.
