Yes.
Yes, "I didn't know that" is a complete sentence, not a fragment. It contains a subject ("I") and a predicate ("didn't know that"), expressing a complete thought. A sentence fragment typically lacks one of these elements or does not convey a full idea.

Begin with a capital letter and end with a punctuation mark. Include at least one subject and one verb. That is how to write a complete sentence. I don't know definition of a "correct" sentence.

To determine which passage is a complete sentence, look for a subject and a verb that express a complete thought. A complete sentence may also have an implied subject, often seen in commands. Without the actual passages to evaluate, I can't specify which one is complete, but remember, complete sentences convey a clear idea and do not leave the reader hanging.
