Answer:
Diego is: (A) not liable, because Denise breached the good faith duty of cooperation.
Step-by-step explanation:
"This is because every contract contains an implied duty of good faith and fair dealing in the performance and enforcement of the contract. Most executives and companies—and even attorneys—however, do not realize that this duty may require that parties not interfere with or fail to cooperate in the other party’s performance. This is important because even if your contract does not explicitly require you to cooperate or if your contract does not explicitly state that you must not interfere, the duty of good faith and fair dealing may require you to do so or else you risk breaching the agreement."
