The correct option is A Nawab of Oudh
In the First Rohilla War, which took place in 1773–1774, Warren Hastings, British governor-general of Bengal lent East India Company’s troops to the nawab of Oudh (Ayodhya) thus helping him in defeating the Rohillas. The Rohillas under Hafiz Rahmat Ali Khan were defeated by Colonel Alexander Champion on 23 April 1774 at the Battle of Miranpur Katra.
