'Retinue' refers to a group of attendants or followers who accompany and serve an important person, such as a royalty, dignitary, or noble. It describes the entourage or staff who travel with and support someone of high status. 'Attendants' is the correct answer as it directly refers to the people who serve and accompany an important person. The other options (Palace, Queen, King) refer to places or titles rather than the group of servants.
