What condition results from Vitamin B9 deficiency?

Rickets
Beriberi
megaloblastic anemia
pernicious anemia

The correct answer is: megaloblastic anemia

Megaloblastic anemia is a condition that results from Vitamin B9 deficiency. Megaloblastic anemia is a blood disorder that leads to the production of large, abnormal red blood cells that have impaired oxygen-carrying ability. This causes symptoms such as fatigue, weakness, shortness of breath, and pale skin. Rickets (A) is caused by Vitamin D deficiency, Beriberi (B) is caused by Vitamin B1 deficiency, and pernicious anemia (D) is caused by Vitamin B12 deficiency. Therefore, these options are incorrect as they refer to deficiencies in other vitamins which cause different conditions.
