The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Homologous Organs**: Homologous organs are those that share a common ancestry. They have similar anatomical structures but may serve different functions in different species. This similarity indicates that these organisms evolved from a common ancestor. 2. **Definition of Divergent Evolution**: Divergent evolution occurs when related species evolve different traits or functions from a common ancestor. This happens as species adapt to different environments or ecological niches, leading to variations in their structures and functions. 3. **Examples of Homologous Organs**: A classic example of homologous organs is the forelimbs of mammals such as humans, whales, bats, and cheetahs. Despite having similar bone structures (humerus, radius, ulna, etc.), these forelimbs serve different functions: grasping in humans, swimming in whales, flying in bats, and running in cheetahs. 4. **Conclusion**: Since homologous organs arise from a common ancestor and evolve due to divergent evolution, the correct answer to the question is that homologous organs support **divergent evolution**. **Final Answer**: Homologous organs support **divergent evolution**. ---
