Which of the following could be considered consideration in a contract?

Consideration in a contract refers to something of value that is exchanged between the parties involved. This could take various forms, which are not limited to just one category. The correct answer acknowledges that consideration can encompass personal property, money, and promises of service.

When one party provides personal property, this is a tangible item of value. Money represents a common form of consideration that is easily understood and universally accepted for various transactions. Additionally, a promise of service constitutes a commitment to perform a task or provide a benefit, which holds value to the other party.

Thus, the correct option indicates a comprehensive understanding of the concept of consideration, which can include multiple types of valued exchanges, thereby solidifying the contractual agreement between the parties. Each of these elements—personal property, money, and promises of service—can serve as valid forms of consideration in different contractual scenarios.
