Sickle cell anemia is a condition characterized by misshapen red blood cells that reduce the body's ability to carry adequate oxygen. Sickle cell anemia is best described as which of the following?
Correct Answer: B
Rationale: Sickle cell anemia is best classified as a hereditary disease, as it is caused by a genetic mutation inherited from parents. This condition is passed down through families, specifically through an autosomal recessive inheritance pattern.
Option A, a congenital disease, refers to conditions present at birth, but not all congenital diseases are hereditary.
Option C, an infectious disease, is caused by pathogens like bacteria or viruses, which is not applicable here.
Option D, a lifestyle disease, involves conditions influenced by personal habits, such as diet or exercise, which does not relate to the genetic nature of sickle cell anemia.
