What is a complete sentence?
A sentence is considered to be full when it has a subject , a verb , and a complete thought .
The noun or pronoun that either performs the action of the sentence or receives its action is referred to as the subject in a sentence. A sentence's verb determines how it will be said.
A subject and a verb are necessary for a complete sentence . A whole statement can be written in as little as two words, as in the following example: I am. A sentence that lacks a subject, a verb, or both is referred to as a sentence fragment or an unfinished sentence.
At least** one subject** and** one predicate**, which make up an independent clause, must be present in every complete sentence.
Hence,** option (B)** is the complete sentence.
