The correct answer is (b). Dastoor was a judicial fee paid to the Chand administration. It was a fixed amount that was paid to the government for each case that was heard. The fee was used to cover the costs of the court system and to pay the salaries of the judges.
Land revenue was a tax that was paid on the land that people owned. It was a percentage of the value of the land that was paid to the government. The tax was used to fund the government and to provide services to the people.
Customary fee was a fee that was paid for certain services that were provided by the government. For example, a fee was paid to get a marriage license or to register a business. The fees were used to cover the costs of providing the services.
None of the above is not the correct answer because it does not describe what Dastoor was.
