  • B
    Non-random evolution
  • C
    Adaptive radiation

Answer

  1. Convergent evolution

Explanation:

Convergent evolution occurs in an unrelated group of organisms. It is the development of similar functional structures but in unrelated groups.

The process of evolution of different species in a given geographical area starting from a point and literally radiating to other areas of geography is called adaptive radiation. Natural selection is the basis of evolution.
