Sarah Worked for Southwestern Botanical Gardens and Loved Her Job

Sarah worked for Southwestern Botanical Gardens and loved her job and loved her coworkers. Five years ago, her employer did not pay her for a week's work, thereby breaching her employment contract, because funds were very low. She decided that she would let it slide because she wanted to see the company make it through a difficult time. However, times have changed and the management has changed and the current managers does not value its employees or its central mission as it had previously. Moral is low and employees are leaving left and right. Sarah, wants to leave now in protest and she is considering suing for the old breach of contract case she could have pursued five years ago just to punish them and get as much money out of the company. When Sarah approaches an attorney about this, he informs her that she can no longer bring the lawsuit because she waited too long and it would be unfair to hold them currently responsible for past bad action. To which law is the attorney referring meant to avoid this situation?

A) Statute of repose
B) Statute of limitations
C) Statute of frauds
D) Statutes of timeliness
