The correct answer is C ) among
Step-by-step explanation:
In grammar, words such as in, for, to, among, about, out of, etc. are known as prepositions, these are used to connect different elements in a sentence as each of them has a particular meaning. In the case of the preposition "above" this means "in the middle of" or "as part of" and it is used to describe objects or places that are in the middle of others or individuals that are part of a group, different from "in" that is used for objects that are within something. This implies, in the sentence " visited by Europeans and he had many strange adventures (10) the almost unknown tribes of Asia" the preposition that completes the sentence is "among" as it refers to an individual that becomes part of a group (unknown tribes of Asia) and the preposition that express this is among rather than for, out of or in.
