When can an offeror revoke their offer?

The correct answer is that an offeror can revoke their offer at any time before it is accepted. This principle is rooted in contract law, which states that an offer remains open and can be retracted until the moment the offeree communicates acceptance to the offeror. Once the offer is accepted, a binding contract is formed, and the offeror no longer has the right to revoke the offer without facing potential legal consequences.

In this context, while the other choices suggest specific scenarios or limitations regarding the timing of revocation, they do not accurately reflect the broader principle of contract law that allows for revocation at any point before acceptance. Thus, understanding the ability to revoke an offer up until its acceptance is crucial for both offerors and offerees in real estate transactions and other contractual agreements.
