This option does not accurately describe the status of the contracts. While it mentions a closing period, the essence of the question revolves around whether the contracts have been fulfilled or executed, rather than just the timing of closing.

The term "fulfilled" implies that all parties have completed their obligations under the contract. However, in legal terminology, "executed" specifically refers to the completion of all contractual duties, indicating that the contract's terms have been fully realized, making "executed" a more precise choice.

A voidable contract is one that may be validated or voided at the discretion of one party, typically due to issues such as lack of capacity or misrepresentation. In this case, the heir, upon reaching legal age, has the capacity to enter into binding agreements, so the contracts are not voidable.

An executory contract is one where some future act or obligation remains to be performed. Since the sale has already occurred and the contracts have been completed, this term does not apply to the current situation, which describes a completed transaction.
