Which of the following is an incorrect option with respect to homologous organs?

Homologous organs have similar origin and structure, but their function is different. 

This means that while homologous organs share a common origin and evolutionary history, they may have evolved to perform different functions over time due to divergent evolution.

"Function is different" is a correct statement because homologous organs in different species may have different functions due to divergent evolution. "Shows adaptive radiation" is also a correct statement, because homologous organs may be part of an adaptive radiation pattern, in which a group of species evolve rapidly and diversify into many different forms in response to environmental changes. "Exhibits divergent evolution" is also an accurate statement, because homologous organs are the result of divergent evolution, which occurs when a group of species evolves into different forms over time due to differences in selective pressures.
