The heir to a large estate will be of legal age within 30 days. The heir lists for sale with a broker one of the properties held by the estate. The broker knows of a buyer for the property and sells it within 24 hours of listing

This option is incorrect because it suggests a timeline for closing rather than addressing the status of the contracts. The timing of the closing does not determine whether the contracts are executed. Execution refers to the completion of the agreement terms, which is already accomplished by the sale within 24 hours.

While "fulfilled" may seem appropriate, it implies that the terms of the contract are completed, but does not specify the status of the contracts as "executed." In legal terminology, "executed" is the precise term used when all obligations in a contract have been met, making it the more accurate choice in this context.

A voidable contract is one that may be legally canceled by one party due to certain conditions, such as a lack of capacity to contract. In this case, while the heir is not yet of legal age, the sale has proceeded, thus negating the voidable status. The contracts are not voidable since they have been executed upon the sale.

An executory contract refers to agreements where one or more parties still have obligations to fulfill. Since the broker has completed the sale and all terms have been met, the contracts are not executory. They are fully executed, indicating that no further actions are required from the parties involved.
