Which one of the following is the correct chronological order of the battles fought in India in the 18th Century?

The correct answer is B because of the following timeline of the four key battles:

1. Battle of Ambur (1749): This was a major battle of the Second Carnatic War where the French forces along with Muzaffar Jung and Chanda Sahib defeated the Nawab of Arcot.

2. Battle of Plassey (1757): The British East India Company led by Robert Clive defeated the Nawab of Bengal, Siraj-ud-Daulah, establishing British influence in Bengal.

3. Battle of Wandiwash (1760): A decisive battle during the Third Carnatic War where the British forces defeated the French, effectively ending French colonial ambitions in India.

4. Battle of Buxar (1764): The British East India Company defeated the combined forces of Mir Qasim, Shuja-ud-Daulah, and Shah Alam II, solidifying British rule over North India.

The chronological sequence 1749, 1757, 1760, and 1764 corresponds exactly to option B.
