How long does the offeror have to withdraw the offer after it has been signed and presented?

The duration that an offeror has to withdraw their offer after it has been signed and presented ultimately depends on whether the offeree has accepted the offer. As long as the offer has not been accepted, the offeror retains the ability to withdraw their offer at any time. This means that as long as the offeree has not explicitly accepted the offer, the offeror is free to change their mind and withdraw the offer without any legal repercussions.

This principle underscores the idea that an offer is not a binding contract until it has been formally accepted by the offeree. Acceptance must be unequivocal and communicated to the offeror. Therefore, until that acceptance occurs, the offeror is in a position to reconsider their proposition.

In contrast, the other options suggest specific time frames or conditions that are not accurate in the context of general contract law regarding offers. While some offers may specify a time limit for acceptance, unless that specific timeframe is previously established and accepted by both parties, the offer can be withdrawn by the offeror at any time before acceptance.
