Detailed explanation-1: -The competitive exclusion principle tells us that two species can’t have exactly the same niche in a habitat and stably coexist. That’s because species with identical niches also have identical needs, which means they would compete for precisely the same resources.

Detailed explanation-2: -According to the competitive exclusion principle, no two species can sustain coexistence if they occupy the same niche. This means that if the species competes for the same species, one will be more successful and one will eventually die out.

Detailed explanation-3: -The competitive exclusion principle also referred to as Gause’s law states that two species in the same ecosystem but different niche competing for the same resource cannot coexist at constant population values if other ecological factors remain constant. Thus, the correct answer is option B.
