The correct Answer is:
To determine which factors can lead to the formation of endemic species in unaffected areas, we need to analyze each option provided: 1. **Climatic Changes**: - Climatic changes can alter the environment in specific areas, leading to adaptations in species that can survive in the new conditions. If certain species adapt to these changes in one area, they may become unique to that area, leading to the formation of endemic species. However, if the changes are widespread, they may not necessarily lead to endemism in unaffected areas. 2. **Destruction of Habitats**: - When habitats are destroyed in certain areas, the species that cannot adapt or migrate may become extinct in those areas. If some species survive in unaffected areas, they may evolve differently due to the lack of competition or predation, leading to the formation of endemic species in those unaffected regions. 3. **Introduction of New Competitor Species**: - The introduction of new competitor species can lead to competition for resources in certain areas. If native species are outcompeted and decline in those areas, the remaining populations in unaffected areas may evolve independently, potentially leading to the development of endemic species. ### Conclusion: Based on the analysis: - **Destruction of habitats** is the most likely factor to lead to the formation of endemic species in unaffected areas, as it can isolate populations and create unique evolutionary paths. ### Final Answer: The factor that will lead to the formation of an endemic species in the unaffected areas is **(ii) Destruction of habitats**. ---
