Which of the following is an example of prior consideration?

The correct example of prior consideration is illustrated by receiving a car for work done in the past. Prior consideration refers to benefits or agreements that were provided before the current contract or promise was made. In this context, a car being given as a reward for labor already completed signifies that the consideration (the work performed) occurred prior to the exchange (receiving the car). This scenario highlights the essence of prior consideration, where the commitment from one party (the act of giving the car) is based on an obligation that has already been fulfilled by the other party (the work completed).

In contrast, the other choices do not represent prior consideration effectively. Submitting a proposal for work describes a potential future agreement rather than a past obligation met. Promising a bonus for past labor indicates a future promise based on past work but lacks the definitive exchange of consideration already established at the time of promise. Offering services in exchange for payment describes a current transactional relationship where both parties are offering something in the present rather than referencing a completed action from the past. Thus, receiving a car for work done is unique in directly linking a completed action to a tangible benefit, exemplifying prior consideration.
