Answer: Option A
:
A
Elephants are a classical example of organisms following K strategy for growth. Since they are so large and live in stable and predictable environments, their population size seldom decrease. Elephants also have a very long life. And therefore they do not need to high growth rate. However, since they grow at a slow pace, elephants invest a lot at parental care for their offsprings, thus ensuring a stable population size.
