Final answer:
An offeree can make certain their offer is kept open with the offeror by requesting an option contract or providing a counteroffer.
Step-by-step explanation:
In order for an offeree to keep their offer open with the offeror, they can request an option contract. An option contract is a contract that gives the offeree the right, but not the obligation, to accept the offer within a certain period of time. This allows the offeree to keep the offer open while they consider their options.
If the offeree accepts the offer immediately, it means they are accepting the offer as it is and closing any opportunity for further negotiation or changes to the terms. Providing a counteroffer, on the other hand, allows the offeree to propose different or modified terms to the offeror, effectively keeping the negotiation process open.
Rejecting the offer, as option D suggests, would not serve the purpose of keeping the offer open.
