• C. Gause
• D. Darwin

Answer 1

Answer: (C)

Gause

Two or more species with close niche requirements cannot exist indefinitely in the same area as sooner or later they come into competition for possession of it. This is called as Gause's competitive exclusion principle, which state that an ecological niche cannot be simultaneously and completly occupied by established populations of more than one species. Two species can live in same habitat but not in the same niche. More siimilar the two niches are, severe the competition is.

So, the correct answer is 'Gause'.
