Explanation
The colon indicates that the purpose will agree with the information in the second part of the sentence, where the young audience is learning advanced vocabulary; a word that means something like teaching would make sense. Both obfuscating and mystifying are nearly the opposite of what you’re looking for, so eliminate choices (B) and (F).
Neither aggrandizing, which means making larger or more powerful, nor ephemeral, which means short-lived, is supported by the sentence, so eliminate choices (D) and (E). Both didactic and edifying can mean intended to instruct, so choices (A) and (C) give you appropriate, equivalent sentences.
