The correct option is B Fateh Hyder
Tipu's son Fateh Hyder was proclaimed as the king of Vellore. Fateh Hyder was also known as Shezada Hyder Ali. After the fall of Seringapatam and death of Tipu Sultan on 4 May 1799, Shezada Hyder Ali and other family members were sent to the Vellore fort on 19 June 1799 and kept under custody of the East India Company. On July 10, 1806, at the marriage of one of Tipu Sultan's daughters at the Vellore fort, Indian soldiers staged a revolt known as the Vellore Mutiny, opening fire in the fort, killing several army officers and taking control of the fort's arms and ammunition. They pulled down the Union Jack flag, hoisted the Royal Tiger Flag of Tipu Sultan in its stead, and declared Shezada Hyder Ali as their king.
