The correct answer is C. Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth.
Explanation:
In biology, k-selected species are species that have stable populations although they do not give birth to multiple offspring at once and individual offspring are mainly big animals that require more time to mature this makes parents invest more time and effort in them to guarantee they survive. According to this, giraffes can be classified as k-selected species because they usually have limited offspring (Giraffes rarely give birth to twins), they seem to mature slowly and offspring requires more care and time (giraffes begin mating at 6-7 years of age) and they are large when they are born (Giraffes are approximately 6’ tall and weigh 150 lbs at birth).
However, the fact "Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth" does not support the idea these animals are k-select species because this shows rapid maturation and little time and effort invested which is the opposite to k-selected species.

Answer:
D. Specialist Species
<h2>
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?</h2>
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
