Final answer:
Hemorrhagic anemia is caused by blood loss due to bleeding, leading to the destruction of red blood cells. This is distinct from hemolytic, aplastic, and pernicious anemias, which have different underlying mechanisms. The correct answer is B. Hemorrhagic.
Step-by-step explanation:
Hemorrhagic anemia is caused by increased destruction of red blood cells due to an individual having an external or internal bleed. Conditions such as ulcers, hemorrhoids, gastritis, and certain gastrointestinal cancers can lead to this type of anemia.
Unlike hemolytic anemia, which involves the inherent destruction of RBCs, or aplastic anemia, characterized by the insufficient production of RBC stem cells, hemorrhagic anemia specifically results from blood loss. Pernicious anemia, also a type of anemia, is connected to vitamin B12 deficiency and does not result from blood loss. Therefore, based on the provided information, the correct answer to the question is 'B. Hemorrhagic'.
