The correct example of a homologous pair of body parts from the options provided is:
**A human skull and a cat skull.**
Homologous structures are those that share a common ancestry, even if their functions may differ. Both the human skull and the cat skull are derived from a common ancestor in the mammalian lineage.
In contrast:
- A fish gill and a human lung are not homologous; they are examples of analogous structures (different evolutionary origins but similar functions).
- A bird wing and a bee wing are also analogous structures (different lineages with a similar function).
- A shark tail and a dog tail, while they serve similar functions, evolved independently in very different lineages and are not considered homologous.
