C Correct answer
Explanation

The presence of large, immature, nucleated erythrocytes without haemoglobin indicates megaloblastic anaemia, which is caused by a deficiency of vitamin B12 (cobalamin) and folic acid. Iron deficiency typically results in microcytic, hypochromic anaemia rather than large megaloblastic cells. Supplementing with folic acid and cobalamine addresses the root cause of this specific type of anaemia.

Identify the vitamin which helps to cure anaemia.

  1. Vitamin A

  4. Vitamin E
Reveal answer Fill a bubble to check yourself
B Correct answer
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'.
