Answer:
Explanation:
The correct answer is:
a. "I need to start eating more red meat or liver."
Pernicious anemia is primarily caused by a deficiency of vitamin B12, which can occur due to impaired absorption in the gastrointestinal tract, often because of a lack of intrinsic factor, a protein necessary for the absorption of vitamin B12 in the intestines. Red meat and liver are rich sources of vitamin B12. Therefore, increasing the intake of these foods can help supply the body with adequate amounts of vitamin B12, which is essential for treating pernicious anemia.
