Final answer:
Consular beige RAICs are used by personnel with consular privileges and go to option b) Consular Services. These cards provide access to restricted areas for those involved in consulate-related duties.
Step-by-step explanation:
The RAICs, which stands for Restricted Area Identity Cards, are an essential component for maintaining security at airports. These cards are used by personnel who need to gain access to restricted areas within an airport. In the context of the acronyms provided, and the options listed for where the consular beige RAICs would be used, the most appropriate place would be B) Consular Services.
This is because the beige RAICs usually indicate that the holder has consular privileges, meaning their work is related to consular activities such as assisting citizens from their home country, issuing visas, etc.
Given these RAICs are used to identify individuals with consular duties, they would not typically be applicable to Customs, an Air Traffic Control Tower, or International Arrivals, since those areas are managed by different categories of airport or government staff with their own specific RAICs.
