The correct option is A The Treaty of Saibai
The first Anglo-Maratha war was fought between the British East India Company and Maratha Empire in India. The combined Maratha forces fought with the forces of the British and Raghunath Rao at Wadgaon. The British were badly defeated and this resulted in the signing of the Treaty of Saibai. Under its terms, the Company retained control of Salsette and Broach and promised to support Marathas in case they attack Hyder Ali of Mysore and retake the territories of Carnatic.
