根据短文，回答题：The College of Arms is an official regulatory commission established in 1484 by King Richard Ⅲ．Its purpose is to design and register new coats of arms and to establish and confirm pedigrees，particularly for families of English and Welsh Line descent．It does not receive funds from tlle government；it is kept in business(5)via the fees it charges，and the heralds who perform the services are paid small salaries by the queen．
It may seem an anachronistic service in the twenty-first century，but in 2005， Camilla，the Duchess of Cornwall，requested and received a new coat of arms to
denote her role as wife of the heir to the throne．The arms consist of an amalgam
(10)of her father’s existing arms；the arms of her husband，tlle Prince of Wales；and a crown with a single arch，signifying since l661 a noblewoman’s position as the consort of the heir apparent．
Consider each of the choices separately and select all that apply．
Based on the information given in the passage，which potential customers would be most likely to need the services of the College of Arms?
