Explanation
This answer is correct because according to FINRA Rule 3270, a registered representative must notify their firm in writing of any outside business activity (OBA) that involves compensation or the reasonable expectation of compensation from another person, or that may be viewed by customers or the public as part of the member's business. However, if the OBA does not involve any of these factors, then the notification is not required. In this case, Reagan's role as the Chief Revenue Officer of a charitable organization may not involve any compensation or any connection to her securities business, especially if none of her colleagues from the charity become clients. Therefore, she is not required to inform her dealer of this outside activity.
