The Battle of Wandiwash (1760) was decisively won by the British East India Company under General Eyre Coote against the French, ending French colonial ambitions in India. Option A is wrong because Mir Jafar was betrayed by Clive at Plassey (1757), not Buxar (1764). Option C confuses Chelianwala (1848, Sikhs vs British) with Dalhousie. Option D is wrong because Kharda (1795) was Nizam vs Marathas, not East India Company.
