Which of the following options is a complete sentence?

Question

Quizplus · Accepted Answer

Every sentence must contain a subject and predicate.
The subject of a sentence is the person, place, thing, or idea that is doing or being something. You can find the subject of a sentence if you can find the verb. Ask the question, "Who or what is performing the action in the sentence?" and the answer to that question is the subject.
The predicate is the part of a sentence or clause containing a verb and stating something about the subject.
"My friend John ate a salad before the chicken." is correct because the subject is "My friend John" and the predicate is "ate a salad before the chicken."
Eating a salad, my friend John before chicken. This sentence does not express a complete thought because the second part of the sentence is missing a verb.
My friend John, chicken after the salad. This sentence does not express a complete thought because it does not have a verb.
Eating before the chicken, my friend John a salad. This sentence does not express a complete thought because the second part of the sentence is missing a verb.
