Answer:
c. Vitamin B12 deficiency
Explanation:
Vitamin B12 deficiency is the cause of many diseases, from anemia to thrombosis. This deficiency is not common in the US, however, it is easily caused by inadequate gastric acid secretion secondary to gastric resection, use of drugs that suppress gastric acid, or gastric infection by Helicobacter pylori.
Vitamin B12 is essential for red blood cell formation, integrity and maturation. In their absence, they increase in volume. In the bone marrow - where they are produced - the number of cells increases so much that the appearance simulates that of leukemias.
It is a necessary vitamin for the development and maintenance of nervous system functions. Without it, the myelin that covers the nerves (as the protective cap does with the electrical wires) suffers wear that is called demyelination, a process that occurs in both peripheral nerve neurons and those in the white matter of the brain.
The main source of B12 is in animal foods. But to absorb it, the digestive tract depends on intrinsic factors present in a special group of stomach cells (parietal cells) and receptors located in the ileum.

Active absorption :- It is a up stream absorption in which use of specified Protein along with ATP is used to absorb substance like ions etc. Active absorption occur against the concentration gradient
Facilitated diffusion :- It is a down stram absorption in which use of special protein is there but no ATP is used to absorb substance like water in plant cell . Facilitated diffusion occur through concentration gradient
Diffusion :- It is a down stream absorption in which no requirement of special protein and ATP molecules is there to absorb substance like glucose etc . Diffusion occur through concentration gradient.
