Correct option (d)

One of the key factors promoting species variety in an environment is competition. When two species compete for the same resources, such as food, water, and shelter, this is referred to as interspecific competition. 

Intraspecific competition is the struggle for resources among members of the same species. Competition's impact on species diversity is influenced by its level of intensity and length.

The diversity of species will decline in an environment where competition is fierce and resources are scarce. 

Because they will outcompete other species for resources, the more competitive species will see a decline in number. As a result, some species may go extinct and a few highly competitive species may dominate the ecosystem.

On the other hand, if resources are plentiful and competition is mild, more niches will be accessible for a variety of species, which will increase species diversity. In this case, each species can focus on using particular resources, which lessens direct competition between them. Numerous species may coexist as a result in the environment.

Therefore, it may be inferred that the impact of competition on species diversity is complex and depends on a number of variables, including the availability of resources, the level of rivalry, and the length of the competition.
