Option c is the correct answer. Iqtadars or Muqtis after meeting his and army's expenses had to send the surplus revenue to the Centre. This surplus amount was called fawazil. The demand to send the excess amounts (fawazil) to the diwan-i wizarat was symbolic of the trend towards centralization. The muqti had to submit accounts of their realisation and expenditure to the treasury. Auditing was severe to prevent fraud.
