Quizplus · Accepted Answer

When an offeree is not interested in an offer, the simplest way to indicate this is by rejecting the offer. A rejection is a clear and unambiguous statement that the offeree does not intend to accept the offer. This lets the offeror know that the offer has been terminated and that they can explore other options. Revocation refers to the offeror withdrawing the offer before it has been accepted. A counteroffer is a new offer made by the offeree in response to the original offer, while promissory estoppel and option refer to legal concepts related to contracts and offers.
