Correct Answer: folic acid

Solution : The correct option is Folic acid.

Folic acid deficiency can result in anaemia. Folic acid is a B12 vitamin that is required for red blood cell formation. Red blood cells transport oxygen to the tissues of the body. Anaemia can occur when the body does not make enough red blood cells due to a lack of folic acid. Megaloblastic anaemia is another name for folate deficient anaemia. This is due to the fact that the red blood cells generated are bigger than normal and have a deformed shape.
