Final answer:
Under BRRETA, listings will terminate upon the completion of the tasks and duties to the client or, if there is no expiration date, one year after the initial engagement date. Hence, options (A) and (B) are correct.
Step-by-step explanation:
Under the Brokerage Relationships in Real Estate Transactions Act (BRRETA), listings will terminate under certain conditions. Completion of the performance of the task and duties to the client is one condition. Assuming there is no expiration date specified, the listing will terminate one year after the initial engagement date.
The broker cannot unilaterally end the relationship at any time without cause; they must adhere to the terms of the agreement, making Option C incorrect. Moreover, there is no provision for a listing to automatically terminate after two years assuming no expiration date is present, which means Option D is also incorrect.
