Final Answer :
D
Explanation :
Option D is correct because it acknowledges the complexity of gene-environment interactions in determining trait expression. It recognizes that the same gene can result in different behaviors under different environmental conditions and that similar behaviors can arise from different genetic backgrounds due to the influence of the environment.
