Question

In the following question, a passage is given which describes a situation. From the given options, mark the correct inference that can be drawn from the passage. If none of the inferences follow, mark option 5, "None of these" as the answer.
In nearly all human populations a majority of individuals can taste the artificially synthesized chemical phenylthiocarbonide (PTC). However, the percentage varies dramatically-- from as low as 60% in India to as high as 95% in Africa. That this polymorphism is observed in non- human primates as well indicates a long evolutionary history which, although obviously not acting on PTC, might reflect evolutionary selection for taste discrimination of other, more significant bitter substances, such as certain toxic plants.
A) Human beings show the same taste profile as primates. B) Humans prefers substances that are naturally sweet. C) Only a minority of the human population have an indeterminant taste profile. D) A majority of the human population have an indeterminant taste profile.
