Vitamin B12 is an important nutrient that we include in our diet The protein called intrinsic factor is responsible for B12 absorption in the intestine
In the stomach, B12 is separated from animal protein attached to it by gastric acid and pepsin. Then B12 binds with the R protein produced by salivary gland and it transports B12 to the small intestine. When B12 reaches the small intestine, it binds with a protein called intrinsic factor. Intrinsic factor allows Vitamin B12 to get absorbed in the small intestine
So the correct answer is: intrinsic factor
All other options are wrong because :
Erythropoietin is a hormone secreted by the kidney. It is an important factor for erythropoiesis and it has no role in B12 absorption
Interleukin 3 is a protein involved in cell growth. It regulates hematopoiesis. It has no role in B12 absorption
Transcobalmin: B12 attaches to transcobalamin after its absorption and it carries B12 through the blood.
