Which courtier to the royal family of the city state of mantua wrote a guide that describes how a courtier should act while serving at court? a. castiglione b. cesare borgia c. machiavelli d. cosimo de' medici

The courtier that wrote a guide that describes how a courtier should act while serving at court was Baldassare Castiglione, so option A is correct. Castiglione wrote “The book of the Courtier” and it was published in 1528. The book includes rules of etiquette, and how a courtier should behave, especially at royal courts. The book summarizes the manners and morals that the perfect courtier is expected to have.

The rest of the options are incorrect since none of then wrote a book of manner or etiquette  at court.

i do not know if this question has options, but a main impact of the federal reserve act of 1913, which created the federal reserve bank, was the international use of the u.s. dollar, which soon became the world's leading currency - particularly during world war i, since many nations around the world asked the united states for money.
