Which change has occurred due to REBBA requirements regarding brokerage obligations to customers?

The correct answer is C - Expanded duties owed to customers.

Recently, changes have been made to the Real Estate and Business Brokers Act (REBBA) requirements, which have expanded the duties owed to customers by brokerages. This change has aimed to enhance consumer protection by increasing the obligations and responsibilities that brokerages have towards their customers. Rather than eliminating the concept of duty of care owed to customers, making obligations to customers and clients the same, narrowing the scope of legal obligations, reducing the obligations to only financial matters, or shifting obligations solely to clients, the focus has been on expanding the duties owed to customers, emphasizing transparency, disclosure, and accountability in real estate transactions.
