Which of the following is true about the expiration of an offer to purchase in Missouri?

This statement is incorrect because, in Missouri, if an offer does not specify a time for acceptance, courts typically do not impose a default period of 7 days. Instead, the offer remains open for a reasonable time, which may vary based on the circumstances of the transaction.

This choice is misleading, as withdrawing an offer typically does not result in forfeiture of earnest money unless explicitly stated in the contract or if the buyer’s withdrawal constitutes a breach of agreement. Generally, earnest money is protected until a formal acceptance occurs.

This statement is inaccurate because even if an offer has a time limit, the buyer retains the right to withdraw the offer before it is accepted. The time limit simply dictates when the offer will expire, but it does not restrict the buyer's ability to rescind the offer beforehand.
