The correct option is A Adaptive convergence
Adaptive convergence also called as convergent evolution. It is the process where resemblance between widely different groups occurred. Whereas adaptive divergence is the divergence of new forms from the common ancestor due to environmental change. Progressive evolution is the process where the simple form of organism develops toward complex form and retrogressive evolution is the process where the complex form of organism develops towards simple form. Thus, the correct answer is option A.
