The correct answer is C. Joan wants to go to a mall or an outlet store
Explanation:
A sentence fragment occurs when a set of words does not form a complete sentence because the subject/verb is missing or there is not a complete idea. In the case presented, "Or to an outlet store" is a sentence fragment because this does not have a subject or verb as it has been separated from "Joan wants to go to the mall". This implies the best to make this a complete sentence is to delete the period and add the information "or to an outlet store" to the sentence "Joan wants to go to the mall". According to this, the best correction that integrates the information and is also the most concise is "Joan wants to go to a mall or an outlet store".
