Answer the question below!
Correct answer is option E.i.e B&C
Pernicious anemia is a condition in which the body is unable to absorb vitamin B12 from the gastrointestinal tract. This can occur due to a lack of intrinsic factor, a protein produced by the stomach that is necessary for the absorption of vitamin B12. Gastric bypass surgery can lead to a deficiency of intrinsic factor, and a vegan diet that does not include any animal products can lead to a deficiency of vitamin B12. Therefore, options B and C provide a reasonable cause for pernicious anemia. Option A may cause anemia, but it is not typically associated with pernicious anemia. Therefore, options D, F, and G are not correct.
