Detailed Solution

Concept: Homology demonstrates similar structures and  different functions, which are evidence for evolution. In developmental biology, the embryo develops organs in a similar way.
The homologous organs were created as a result of divergent evolution, which means that although they have a common ancestor and a similar structure, they serve different purposes. The homologous organs can also include the human arm.
Examples of homologous organs include the forelimbs of a cat, lizards used for walking, whales used for swimming, and bats used for flying.
All of the forelimbs mentioned above are modified versions of the same type of bone; only their outward appearance varies as a result of their environmental adaptation.
 Hence, the correct answer is option 3.
