The sentence in question is: "Homo sapiens is one of several species (A) into the genus Homo, but it is the only one that is not extinct."
We are looking for a word that appropriately conveys the idea of placing species into a biological category.
I. grouped (Correct):
"Grouped into" is a standard scientific expression used when referring to classification based on shared traits or taxonomic hierarchy.
II. classified (Correct):
This is another accurate term in biological taxonomy, where organisms are systematically categorized.
III. inclusive (Incorrect):
"Inclusive" is an adjective, not a verb or participial form. It means "not excluding," which does not fit grammatically or contextually in this sentence.
Thus, option (c) is the correct answer.
