A comma splice occurs when two independent clauses are incorrectly joined by a comma to make one sentence. The first step in order to avoid comma splaces is to indentify independent sentences which are those complete sentence that can stand on its own. Independent sentences are clauses with a subject and a verb.
So, the sentence of the options provided which serves as an example of comma splice is option D. Sherri likes to take pictures, she is taking a photography class.
In this case, two independent sentences are incorrectly linked by a comma.
The last sentence is an example of a comma splice since 2 independent clauses are connected by only a comma(it needs a coordinating conjunction after the comma or change it to semicolon or period)
