Correct Answer - Option 1 : Lactic acid

The correct answer is Lactic Acid.

  • Lactic acid, or lactate, is a chemical byproduct of anaerobic respiration, the process by which cells produce energy without oxygen around.
  • The molecular formula of Lactic acid is CH3CH(OH)COOH.
  • Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low.
  • The vitamin B-complex refers to all of the known essential water-soluble vitamins except for vitamin C.
  • These include thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin, folic acid and the cobalamins (vitamin B12).
  • B vitamins play a vital role in maintaining good health and well-being.
