Final answer:
The revised sentence that is a complete sentence is 'I ran out of time and didn't finish'.
Step-by-step explanation:
The revised sentence that is a complete sentence is:
O I ran out of time and didn't finish.
This sentence is a complete sentence because it has a subject 'I' and a predicate 'ran out of time and didn't finish'. It expresses a complete thought and makes sense on its own.
Other options provided are sentence fragments because they lack either a subject or a predicate. For example, option B 'Got distracted and ran out of time' is a sentence fragment because it does not have a subject.
