The sentence that must be revised to eliminate the preposition at the end is C) Where are Katelyn and Ella walking to?
Prepositions are short words that generally show a relationship between a noun or pronoun and other words in the sentence. In this sentence, the use of the preposition<em> to</em> at the end of the question is unnecessary because it is redundant; that is to say, the meaning of the question is already conveyed without the preposition.
