Option b is the correct answer The first Mughal ruler who fought against the British was Aurangzeb. He engaged in the Anglo-Mughal War (1686-1690), also known as Child's War, named after Sir Josiah Child, the governor of the East India Company at the time. The conflict arose due to tensions between the English East India Company and the Mughal Empire over trading privileges and taxes. The war saw battles and blockades along the Indian coast, with the Mughal forces led by Aurangzeb ultimately achieving victory. The East India Company was forced to concede, pay a fine, and renew trade privileges under Aurangzeb's terms. This marked the initial clash between the Mughal Empire and the British on the Indian subcontinent.
