The correct answer is - C. hominoids.
The hominoids are a group of mammals that do not share the same basic features as the other mammals, speaking in the manner of physical appearance only of course.
The hominoids have started to develop in a much different manner than the rest of the mammals, becoming exclusively bipedal, losing their hair for protection, losing their strength even, becoming species without any particular natural defense mechanisms. This type of mammals became the only one that is reliant on its brain power for its survival, and that makes them unique and not like the other mammals.
In many cases, the activity of an enzyme is regulated by Negative feedback where the end product acts as a non competitive inhibitor.
In feedback inhibition the end product of a metabolic pathway acts on the key enzyme regulating entry to that pathway, keeping more of the end product from being produced. The feedback inhibition acts at the first committed step of the pathway, meaning the first step that's effectively irreversible. The pathway steps regulated by feedback inhibition are often catalyzed by allosteric enzymes.

Because if we're simultaneously moving/manipulating two different variables it can be very hard to determine why one variable is changing and why the other is changing. While this can be done with more complicated experimental designs, it usually is the case that scientists will only manipulate one variable and not two different ones.
