What term denotes an offeree's notification agreeing to the terms of an offer?

The term that denotes an offeree's notification agreeing to the terms of an offer is "acceptance." This is a fundamental concept in contract law, where acceptance signifies the agreement of the offeree to the conditions set forth in the offer. For a valid contract to be formed, there must be a clear acceptance of the offer, which indicates that the parties are on the same page regarding the terms. Acceptance can take various forms, such as verbal communication, written confirmation, or even conduct that indicates consent.

In contrast, an "invitation" refers to a request for offers or an expression of interest rather than an acceptance of terms. "Proposal" often denotes an offer itself rather than the acceptance of one. "Consideration" is a separate element of a contract that refers to something of value exchanged between parties, but it does not pertain to the action of agreeing to the terms of an offer. Thus, acceptance is the correct term to describe the offeree's agreement to an offer.
