Answer:
No acceptance has been given
Explanation:
The listing contract has been terminated by the seller and the broker, and broker has received the notification of termination.
The new offer that is now received cannot be valid as the seller cannot accept.
For a contract to be valid there has to be an offer and acceptance. The seller cannot now accept because the listing contract has been terminated.
The only way the contract can go forward is of the contract with the broker is renewed.
