Correct answer: D

Rationale: The correct answer is D. The passage focuses on describing sickle-cell anemia as a painful and inherited disease. It details how the abnormal sickle-shaped cells cause symptoms like bone pain, fever, and fatigue. While bone pain is mentioned as a symptom, it is not the main idea of the passage. Choice A is incorrect. Choice B, which mentions oxygen transport, is not the main idea but a general concept.
