Answer : 1. "केवल A"
Explanation :

The first English factory was set up on the banks of the river Hugli in 1651. By 1696 it began building a fort around the settlement near the factory. The East India company persuaded the Mughal emperor Aurangzeb to issue a farman granting the Company the right to trade duty free. A farman was a royal edict or an order issued by the Emperor. Aurangzeb’s farman had granted only the Company the right to trade duty free. The officials of the Company, who were carrying on private trade on the side, were expected to pay duty. However, they did private trades without paying taxes, causing an enormous loss of revenue for Bengal. This behaviour led to a protest by the Nawab of Bengal, Murshid Quli Khan.
