Correct option (a)

According to Gause's competitive exclusion theory, one species will eventually out-compete and eradicate the other species when two species compete for the same limiting resource in the same niche.

This is because both species are under pressure from competing for the same resource, and the more successful species will have an advantage in obtaining the resource, resulting in the development of its population. 

The number of less successful species will fall as a result of a reduction in resources. The less successful species might eventually become extinct in the region or evolve to fill a different niche where it can thrive more successfully.

Option a is the correct answer.
