Groups of organisms with low biotic potential, such as gray whales, that produce at most one offspring every other year a) are r-selected b) are k-selected c) are not subject to density-dependent limiting factors d) show the initial stages of the extinction process e) have escaped from the processes of natural selection and adaptation

B) K - selected species

Explanation:

Usually, large in size individuals such as whales, hipopothamus, horses and bears are K-selected species. They have a low biotic potential which means, they produce small amount of individuals in the reproduction and possess relatively stable populations.

On the ther hand, species such as fleas, rats, and rabbits (between others) are rated r-selected species, which means they have a high biotic potential; have a large amount of individuals per birth.
