• We were supposed to fill in the given blank with the help of a preposition.
• Let us first understand the meaning of prepositions.
• A preposition is a word that can be used to define the relationship that pertains between the noun or pronoun and the rest of the sentence.
• Here the preposition "in" should be used because it is used when we refer to someone's location.
