Answer:
Option (D) Graham is not allowed to sue Alice, having lost his right to sue her.
Explanation:
The reason is that the plaintiff can only sue the party who damage him / her in a limited period of time. Because the longer the period has lapsed the greater are the chances that the court would think that the plaintiff has forgiven the other party. So once you have forgiven the other party you have no right to sue the company again. The statute of limitations establishes the period in which the case by the plaintiff must be filed against the defendant. So we can see that Graham is unable to sue Alice because the time of suing Alice is passed. It has been 4 years now, Graham has no right to sue Alice now.
