Respuesta :
A. participate in our beneficence
Throughout the letter it is obvious that Emperor Qian Long feels as though he is doing a favor for the European nations by providing tea, silk, and porcelain. Of the options given "participate in our beneficence" is the best choice to show a superior attitude. Beneficence is an act of charity or mercy. This use of the word beneficence proves that the Emperor feels that his "Celestial Empire" is superior to the European nations.
