K-strategists might include which species?
Kamila [148]

Potential K- strategists include humans.

K- strategist:

The term "K-selected" or "K-strategist" refers to species whose populations vary at or close to the carrying capacity (K) of the ecosystem in which they live. Compared to r-selected species, K-strategist species have remarkably constant populations and generate relatively few offspring, but those offspring typically grow to be rather big. Lengthy gestation durations of many weeks, slow development (and hence prolonged maternal attention), and long longer lifespans are traits of K-selected species. Additionally, they typically live in ecological groups that are generally stable, including premature or climax forests.

R-strategist:

They are creatures that have high reproduction rates followed by high death rates, resulting in populations with wildly variable numbers, according to the concept of r-selected species (or r-strategist). This term is based on the concept of "r," a variable in the ecology of animal populations that denotes a species' maximal reproductive potential. The populations of r-selected species will be small outside of the mating season. R-selected organisms begin to generate a lot of progeny as soon as reproduction begins. 

Therefore it is concluded that the final choice is option C, i.e., humans.
