When is acceptance considered valid?

Acceptance is considered valid when it is communicated to the offeror. This principle is rooted in contract law, which stipulates that for an acceptance to be effective, it must be conveyed to the person who made the offer. The communication of acceptance does not solely rely on the method used, whether verbally, in writing, or through behavior; what matters is that the offeror is made aware of the acceptance. This requirement exists to ensure that both parties have a clear understanding and agreement to the terms proposed, facilitating clear communication and preventing misunderstandings.

The other options present scenarios that may suggest acceptance but do not fulfill the necessary requirement of communication. For instance, inferred acceptance based on circumstances might not provide the offeror with the definitive acknowledgment that is essential for forming a binding contract. Similarly, while verbal expressions or written documentation are valid forms of communicating acceptance, the core necessity remains that the acceptance be explicitly communicated to the offeror for it to hold any contractual validity.
