Answer: C. Reformation
Explanation: A non-compete agreement or clause is a legal binding entered into by two or more parties which restricts the parties from being in competition with the other usually through the sale of similar product. However, in the context above, since the non-compete clause has been breached by Jack, and the judge feels the time constraint in the clause was unreasonably long, The reformation process will be best to remediate the situation, which refers to the change or alteration of the terms of an existing document using the judicial process and requires the conformation of the parties involved.
