Which of the following statements is correct?

a- In the diwan-i am the Mughal emperors discussed confidential matters

b- In the diwan-i khas the primary business of the emperor's government was conducted.

Neither of them is correct.

After spending an hour at the jharoka, the emperor walked to the public hall of the audience (diwan-i am) to conduct the primary business of his government. State officials presented reports and made requests. Two hours later, the emperor was in the diwan-i khas to hold private audiences and discuss confidential matters. High ministers of state placed their petitions before him and tax officials presented their accounts. Occasionally, the emperor viewed the works of highly reputed artists or building plans of architects (mimar).
