Answer: B

Explanation:

Anemia is a condition characterized by a deficiency of red blood cells or hemoglobin in the blood, leading to a lack of oxygen being carried to the body’s tissues. This can result from a deficiency of iron, vitamin B12, or folate, among other causes. The other options refer to different conditions: Angina: Chest pain caused by reduced blood flow to the heart.

Ischemia: Restricted blood supply to tissues, causing a shortage of oxygen needed for cellular metabolism.
