Final answer:
The counteroffer voided the original offer in contract law.
Step-by-step explanation:
In contract law, a counteroffer is a response by the offeree (the party to whom an offer is made) that contains new or different terms from the original offer. When a counteroffer is presented, the original offer is considered terminated or voided. Therefore, if a counteroffer is made and accepted, a new agreement is formed, effectively replacing the original offer.
