Which license is registered to sales associates who are registered under one owner/developer?

The correct answer is the group license. A group license is specifically designated for sales associates who work under a single owner or developer. This type of license allows the sales associates to represent multiple properties or projects owned by that same owner or developer without the need for separate licenses for each property.

In contrast, a sales license is more general and does not denote the relationship with a specific owner or developer. A broker license is required for individuals who want to operate independently or manage a real estate business, and it does not apply to sales associates working under one owner or developer. The term "universal license" is not commonly used in the context of real estate licensing and does not refer to any recognized license type. Therefore, the group license is the most appropriate and relevant answer in this context.
