Which elements must be included in an agency and counsellor's identification?

The correct choice emphasizes the essential elements that must be reflected in an agency and counsellor's identification. Specifically, it is necessary to include the travel agent's name, address, and registration numbers. This information is critical as it ensures transparency and accountability in the travel industry, allowing clients to verify the legitimacy of the agency or counsellor they are engaging with.

Including the travel agent's name provides a point of contact, while the address gives a physical location for the agency, reinforcing trust with clients. The registration numbers are particularly important as they signify that the agent or agency is licensed and operates under the regulations of the jurisdiction, thereby complying with industry standards.

Incorporating a business plan, office hours, or customer feedback does not fulfill the identification requirements set by regulatory bodies, which focus on providing clear and verifiable information about the agency or counsellor. Therefore, while those elements may be useful in other contexts within the travel service sector, they do not meet the mandatory identification criteria.
