'Animal protein factor', 'chick growth factor', and 'anti-pernicious anemia factor' are all other names for which vitamin?
- Vitamin B1 (Thiamine)
- Vitamin A (Retinol)
- Vitamin C (Ascorbic acid)
- Vitamin B12 (Cyanocobalamin) ✓ Correct
Explanation:
Correct Answer: Vitamin B12 (Cyanocobalamin)
Vitamin B12 has several alternative names:
- Animal protein factor: Found exclusively in animal-origin foods.
- Chick growth factor: Essential for normal growth in chicks.
- Anti-pernicious anaemia factor: Deficiency causes megaloblastic (pernicious) anaemia.
- Cyanocobalamin: Contains cobalt (Co) as central metal ion.

Cobalt deficiency in ruminants → Vitamin B12 deficiency (rumen microbes cannot synthesise B12 without cobalt). Cobalt-deficient disease: Enzootic marasmus / Pine disease.
