'Convergent Evolution' is shown by :
homologous organs
analogous organs

above three
B.
analogous organs
Convergent evolution is shown by Analogous organs. It is also known as Adaptive convergence or Parallel Evolution whereas Divergent evolution or Evolutionary divergence or Adaptive radiation are shown by homologous organs.
