Correct Answer: Vitamin B₁₂
Vitamin B₁₂ (Cyanocobalamin) has several important alternative names that reflect its biological functions: Animal Protein Factor (APF), Chick Growth Factor (CGF), and Anti-Pernicious Anemia Factor.
Vitamin B₁₂ — All Names & Key Facts

Vitamin B₁₂ — Key Facts

Why Other Options Are Wrong
- Vitamin B₁ (Thiamine) → Anti-neuritic factor; deficiency causes Polyneuritis/Star gazer position
- Vitamin C (Ascorbic acid) → Anti-scurvy factor; not APF or CGF
- Vitamin A (Retinol) → Anti-infective vitamin; not APF or CGF
