Final Answer : C, Explanation :  The fact that adopted children resemble their biological parents in a behavior suggests that genetics play a role in that behavior. This is because adopted children do not share the same environment as their biological parents, but they do share the same genes. Therefore, any similarity in behavior between them is likely due to genetic factors rather than environmental factors. Options A, B, and D do not provide clear evidence for genetic influence on a behavior.
