  Analogous organs arise due to (a) divergent evolution (b) artificial selection      (c) genetic drift                 (d) convergent evolution

Answer:

   (d) Analogous organs arise due to convergent evolution. These are the organs which have similar functions, but are different in their structural details and origin, e.g., wings of insect and bird. The other three options are incorrect, because divergent evolution give rise to homologous organs, genetic drift can contribute to speciation and artificial selection is used to produce improved varieties of animals and plants.
