  1. Vitamin A

  2. Vitamin B12

  3. Vitamin K

  4. Vitamin E

Show answer
Correct Option: B
Explanation:

  • Vitamin B-12 is a water-soluble vitamin, like all other B-vitamins. This means it can dissolve in water and travel through the bloodstream. 
  • The human body can store vitamin B-12 for up to four years. Any excess or unwanted vitamin B-12 is excreted in the urine. 
  • The human body produces millions of red blood cells every minute. These cells cannot multiply properly without vitamin B-12. The production of red blood cells reduces if vitamin B-12 levels are too low. Anaemia can occur if the red blood cell count drops. Hence, Vitamin B12 helps to cure anaemia. 
 So, the correct answer is 'Vitamin B12'.
