Prepositions express relationships, especially location. In this sentence, the word that starts the phrase describing where the dog slept is the preposition. It introduces a location for the action, forming the prepositional phrase “under the table.” The object of that preposition is the noun phrase “the table,” which completes the meaning of the relationship. The other words—“dog” (a noun) and “slept” (a verb)—do not function as a preposition, so they don’t set up a location like this. So the word that conveys the spatial relationship is the preposition, making it the right choice.
