Explanation:

A run - on sentence incorrectly combines two or more independent clauses without proper punctuation or conjunction. "Don't tempt me with that fudge, I'm trying to avoid sugar." is a run - on as it has two independent clauses ("Don't tempt me with that fudge" and "I'm trying to avoid sugar") joined only by a comma. The other two sentences have dependent clauses at the start and are properly formed.

Answer:

Don't tempt me with that fudge, I'm trying to avoid sugar.
