The sentence "Can you believe it? He didn’t tell anyone!'' does not contain an example of a sentence fragment.
Answer: Option C
Step-by-step explanation:
A complete sentence is an assimilation of words with logic connotation. It involves three things a subject, a predicate and an independent thought. An incomplete sentence is identified as sentence fragment. If a sentence lacks either a subject, predicate (verb) or thought, it automatically fails to convey information to the readers.
Sentence Fragments can be accepted in verbal communication, but it is highly criticized in academic writing because they fail to accomplish the effectiveness, and that is why proof-reading is advisable. In this question, option C has a subject, verb and a thought in both the sentences.
