If a group of species lived together in a small area, the carrying capacity of that area would probably collapse quickly? ? k selected or r selected

The answer is K-selected.

The population size of K-selected species is fairly constant in time, unlike the population size of r-selected species. r-selected species are usually bellow carrying capacity and the population size is density independent. On the contrary, K-selected species are usually near or at carrying capacity and the population size is density dependent.

Is there any answer choices?

The correct answer is  b)
