(c) Gause's principle of competitive exclusion can be restated to say that no two species can occupy the same niche indefinitely when resources are limiting. Certainly species can and do coexist while competing for some of the same resources. Nevertheless, Gause's theory predicts that when two species coexist on a long-term basis, either resources must not be limited or their niches will always differ in one or more features; otherwise, one species will outcompete the other and the extinction of the second species will inevitably result, a process referred to as competitive exclusion

Gauses principle of competitive exclusion, also known as Gause's law, states that no two species can occupy the same niche indefinitely for the same limiting resources. This principle was proposed by Russian ecologist Georgy Gause in 1934.
Explanation:
• A niche refers to the role of a species in its ecosystem, including its interactions with other species and its use of resources.
• Limiting resources are those that are in short supply and are necessary for the survival of a species.
• According to Gause's principle, if two species have the same niche and compete for the same limiting resources, one species will eventually outcompete the other and drive it to extinction.
• This is because the more efficient species will be better able to obtain the necessary resources, leaving less for the other species to use.
• Over time, this competitive exclusion will result in the coexistence of species with different niches or the evolution of one or both species to occupy different niches.
• The principle of competitive exclusion has been supported by numerous experiments and observations in ecology.
Significance:
• Gause's principle of competitive exclusion is important in understanding the dynamics of ecological communities and the evolution of species.
• It helps explain why there is such a diversity of species in ecosystems, as different species have evolved to occupy different niches and avoid direct competition with one another.
• The principle also has implications for conservation biology, as it highlights the importance of preserving habitats and resources that are critical to the survival of different species.

In ecology, the competitive exclusion principle, sometimes referred to as Gause's law of competitive exclusion or just Gause's law, is a proposition that states that two species competing for the same resource cannot coexist at constant population values, if other ecological factors remain constant. When two competing life forms attempt to occupy the same niche, only one outcome is possible: One life form will drive out the other. So, option C is correct.
