Final Answer :
C
Explanation :
Twin studies have consistently shown that Alzheimer's disease has a significant hereditary component, with estimates of heritability ranging from 60% to 80%. This means that genetics play a major role in determining whether an individual is predisposed to developing the disease. While other factors such as lifestyle and environmental factors may also contribute to the risk of developing Alzheimer's disease, they do not appear to be as important as genetics. Therefore, C is the best choice.
