An acceptance entails the offeree accepting what?

In contract law, acceptance requires the offeree to agree to every term presented in the original offer without any modifications. This principle is known as the "mirror image rule." When the offeree accepts all terms of the offer exactly as they are, this creates a legally binding agreement. If any terms are altered or if the offeree adds new terms, that response is not considered an acceptance, but rather a counter-offer, which would need to be further negotiated.

In this case, the correct answer reflects the necessity for complete agreement on all terms of the offer for it to be valid. By accepting every term, the offeree confirms their willingness to engage in the agreement as stated, ensuring clarity and reducing misunderstandings between the parties involved.
