Forelimbs of cat, lizard used in walking; forelimbs of whale used in swimming and forelimbs of bats used in flying are an example of

Correct option is C. Homologous organs. Homologous organs are those organs which have similar origin but perform different functions. Forelimbs of cat, lizard used in walking; forelimbs of whale used in swimming and forelimbs of bats used in flying are an example of homologous organs. Analogous organs are those organs which have similar functions but different origins. An example includes wings of insects, bats and birds which are evolved independently. Thus, the correct answer is 'Homologous organs'.
