If a licensed business entity has a change in ownership greater than 25%, the Registrar must be notified __________.

The requirement for a licensed business entity to notify the Registrar after a change in ownership greater than 25% is based on the regulatory framework governing such businesses. When a change of this magnitude occurs, it can significantly impact the structure and operation of the business, which is why prompt notification is mandated.

Notifying the Registrar immediately after the change ensures that the regulatory body is kept up to date with who has ownership control over the entity. This aids in maintaining compliance with statutes and regulations that govern licensing, oversight, and public health and safety.

In this context, options that suggest notifying the Registrar either prior to or within a specified period after the change would not align with the intent of ensuring immediate transparency regarding ownership changes. While these options imply a timeline for notification, they do not fulfill the requirement for immediate accountability that is crucial when significant ownership changes occur. Therefore, immediate notification is the correct and most compliant response in this scenario.
