Correct Answer: Isolation
Solution : The correct option is isolation.
The process that prevents interbreeding between separate species or groups is known as "isolation." Geographic, ecological, behavioural, or reproductive variables can all contribute to this isolation. These processes are essential to the process of speciation, in which new species arise from existing ones, and play a critical role in maintaining the genetic diversity of various species or populations.
