The correct option is A Tippu Sultan
The period of wars ended with the fall of Tippu Sultan. The British took over the Mysuru state and divided into four parts among Marathas, Nizam and themselves. The remaining one part was returned to Mysuru Wodeyars. Krishnaraja Wodeyar III was brought to power. Since, Krishnaraja Wodeyar III was only five year old boy, Poornaiah was appointed as the Diwan of Mysuru.
