Final answer:
The correct answer is b) Wilson's disease, a hereditary disorder causing the body to retain copper and leading to various health issues.
Step-by-step explanation:
The genetic disease where the body is unable to rid itself of copper is known as Wilson's disease. This is a hereditary disorder of copper metabolism, leading to copper accumulation in the body's tissues. This can eventually cause liver damage and other serious health issues. It is important to note that Wilson's disease is different from Hemochromatosis, which is the accumulation of iron rather than copper. Sickle cell anemia involves sickle-shaped red blood cells and Cystic fibrosis is related to mucus buildup in the lungs and other organs. Hence, the correct answer to the student's question is b) Wilson's disease.
