Correct answer
B. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Step-by-step solution
(A) Habitat loss and fragmentation: The most dramatic examples come from tropical rain forests, such as the clearing of the Amazon rainforest for cultivating soya beans. (B) Over-exploitation: Extinction of Steller's sea cow and passenger pigeon in the last 500 years were due to over-exploitation by humans. (C) Alien species invasion: Introduction of Nile perch into Lake Victoria led to the extinction of an ecologically unique assemblage of more than 200 species of cichlid fish. (D) Co-extinction: When a species be
