Step-by-step explanation:
In English Language, sentences are known to be group of words that has a subject and a verb. Sentences give a complete thought. For example, in No. 1 we see that it expresses a complete thought and also contains subject and verb.
Fragments are word groups which are cut out from the main sentence. They do not give complete thought. No. 4 is a clear example of what fragment is.
Run-on are connected by comma or any appropriate punctuation mark. No. 2 is an example of run-on sentence.
