Mabel earns a salary by working a full$-$time job at an advertising firm. Her hours of work are flexible, and she often works on weekends so that she can leave work early and pick up her children from school. Recently, her boss received a compliment from the firm's biggest client, concerning work that Mabel did two months ago. Her boss went to tell Mabel immediately and promised her a $10$ percent bonus in recognition of that work. One month later, Mabel still has not received the bonus. Which of the following correctly describes Mabel's legal right to the bonus?

There is not enough information to make a decision.

Mabel should send an invoice for the bonus because her boss has to pay it$.$

Mabel's bonus is a promise supported by past consideration and therefore she has no legal right to the bonus.

Mabel can continue to do great work and will get the bonus for her future work.

The great work that Mabel did is consideration for the bonus and is therefore a legal debt owed to Mabel.
