the third one, if you add the comma without the when then you would have a comma splice (when you put a comma between 2 independent clauses without a conjunction) adding the when before Cynthia makes the first part a dependent variable and makes it okay to add the comma!

Answer:
C. Comma splice
Explanation:
The sentence contains a comma splice. Two independent clauses are joined together by a comma.
You can fix a comma splice by adding a coordinating conjunction to the sentence: <em>"Your imagination is running away with you, </em><em><u>for</u></em><em> there are no squirrels in the attic." </em>
Another way to fix a comma splice is by changing the comma into a period, semicolon, or even an exclamation point!
