The basic structure of communication is the sentence.
A sentence is a group of words that expresses a complete thought. It typically contains a subject (the person or thing doing the action) and a predicate (the action or state of being).
In communication, sentences are used to convey information, ideas, and emotions. They are the building blocks of communication, allowing us to express ourselves and communicate effectively with others.
For example, when you say, "I love dogs," you are using a sentence to communicate your feelings towards dogs. This sentence contains a subject (I) and a predicate (love dogs) and expresses a complete thought.
In contrast, a word is the smallest unit of meaning and cannot express a complete thought on its own. A paragraph, on the other hand, is a group of sentences that are related to a specific topic or idea. While paragraphs are important for organizing and presenting information, they are not the basic structure of communication.
Therefore, the correct answer is b) sentence.
