Answer:
c. Restitution
Step-by-step explanation:
In contract law, restitution (or restitutionary damages) is a legal remedy that applies to situations where an injured party sues another party in order to recover the same financial position as they were before the damages or injuries occurred. Generally restitution applies to civil cases and sometimes to criminal ones.
In this case, FF wants to recover work that has already been completed, they do not seek any other type of damages resulting from the breach of the contract. This is why restitution applies.
