If a registered broker changes their business address, how long do they have to notify the Real Estate Commission?

When a registered broker changes their business address, they have 10 business days to notify the Real Estate Commission. Option A and C are incorrect because they suggest a shorter time frame than what is required. Option D is incorrect because it suggests a longer time frame than what is required. By choosing option B, the broker can ensure they are following the proper protocol and avoiding any potential penalties or fines for failing to notify the Commission within the designated time frame.
