Homology refers to traits inherited by two different organisms from a common ancestor. The fluke of a whale and the tail fin of a tuna are not homologous structures; they are examples of convergent evolution, where similar features evolve independently in species of different lineages. The other options (B, C, and D) represent true homologies, where the structures or traits are inherited from a common ancestor.
