According to the Registrar's guidelines on advertising, what condition must be met to include a specific property in a listing advertisement?

In accordance with the Registrar's guidelines on advertising, to include a specific property in a listing advertisement, the condition that must be met is to have the written consent of the seller. This ensures that the seller is aware and agrees to have their property included in any advertising materials.

Options A, B, D, E, and F are not correct as they do not directly address the specific condition required by the Registrar's guidelines for advertising a property. Option A is not accurate as commercial properties can be advertised, option B does not focus on the consent of the seller, option D states that the issue is not directly addressed, option E does not specifically mention the seller's consent, and option F states that permission from all involved parties is required, which is not accurate based on the guidelines mentioned.
