What is an object in a sentence?

In a sentence, an object is defined as a noun or pronoun that follows the verb and receives the action of that verb. This means the object is impacted by what the subject is doing. For example, in the sentence "He reads the book," "the book" is the object because it is what is being read by the subject "He." The object is integral in completing the action since it tells us what or whom the action is directed toward.

The other options refer to different elements of sentence structure. The first option describes a subject, which is the noun or pronoun performing the action. The third option pertains to adjectives that modify or describe the subject, and the fourth option refers to a prepositional phrase, which adds additional information but does not serve as an object receiving the action. Therefore, the identification of an object specifically as a noun or pronoun that follows the verb and receives the action is what makes this answer accurate.
