The following sentence contains a comma splice: 'The data suggests a correlation, however, further research is needed to establish causation.' Which of the following revisions best corrects this error?
Correct: B
The original sentence is a comma splice because it joins two independent clauses with only a comma. Using a semicolon followed by 'however' and a comma correctly separates and connects the two clauses. 'And' would need a coordinating conjunction and is semantically weaker. Removing the comma creates a run-on sentence. Moving the comma doesn't fix the fundamental issue.
