Final answer:
The components of a sentence are the subject, predicate, and complement, making option 4) Subject, predicate, and complement correct. The subject names the sentence's topic, the predicate contains the verb, and a complement or object is often included to complete the thought.
Step-by-step explanation:
The components of a sentence include the subject, the predicate, and often, though not always, an object or complement.
Therefore, the correct option from the ones you've provided is option 4) Subject, predicate, and complement.
To clarify these components, the subject of a sentence is usually a noun or pronoun that names what the sentence is about.
The predicate contains the verb, which expresses an action, an occurrence, or a state of being.
When present, an object receives the action of the verb, and a complement can either rename or describe the subject or object, often following a linking verb.
It's also important to note that objects and complements are not always necessary for a sentence to be complete; sometimes a subject and predicate are sufficient.
