Yes, 1.

You are correct. The function of a preposition in a sentence is to relate a noun or pronoun to another word. Prepositions show the relationship between the noun or pronoun and other elements in the sentence. They typically indicate location, direction, time, manner, or other relationships. Examples of prepositions include "in," "on," "at," "under," "to," "from," and "between."

You're on the right track! The correct answer is indeed option 1. Prepositions are words that typically come before a noun or pronoun and establish a relationship between that word and other parts of the sentence. They help indicate location, time, direction, manner, and other relationships. Examples of prepositions include "in," "on," "at," "under," "over," "through," and "between." By using prepositions, we can provide more details about the noun or pronoun and its relation to other elements in the sentence. So, in this case, option 1 is the function of a preposition in a sentence.
