Answer:
C. connect it to the sentence before or after it
Step-by-step explanation:
Dependent clauses fragments are groups of words with a subject and a verb that seem a sentence because they begin with a capital letter and end with a punctuation mark like a period, but that, in reality, are not sentences because they do not express a complete thought. Since they can not express a complete idea on their own, they must be next to a sentence, either before or after it.
