Answer and explanation:
An independent clause is a group of words that can stay alone as a sentence, which means it offers information that makes sense without the help of another sentence. When independent clauses are joined incorrectly, we have what is called a run-on sentence. And, when we join independent clauses without any sort of punctuation, we have a fused sentence. When we join them only with a comma, we have a comma splice. All of the sentences presented in the question are fused with the exception of the comma splice in number 7 . Let's correct them with the options given:
: A period and a capital letter
: A comma and a coordinate conjunction - for, and, nor, but, or, yet, and so.
: A semicolon
: A a dependent word -- after, although, as, as if, because, before, even if, even though, in order to, since, though, unless, until, whatever, when, whenever, whether, and while.
