The correct answer is:
i, ii, iii and v
Organs that are structurally different but perform the same function are called analogous organs. They are a result of convergent evolution. Examples of analogous organs are wings of butterflies and of birds, the eye of the octopus and of mammals, the flippers of penguins and dolphins, Sweet potato (root modification) and potato (stem modification) etc.
Organs that are structurally similar but perform different functions are called homologous organs. They are a result of divergent evolution. It indicates common ancestry. Homology is seen in vertebrate hearts or brains. It is also seen in the thorn and tendrils of Bougainvillea and Cucurbita.
