The correct answer is D. 1746 and 1748.
The First Carnatic War was a conflict fought between the French East India Company and the English East India Company in the Indian subcontinent from 1746 to 1748. The war was part of the larger War of Austrian Succession, which was fought in Europe from 1740 to 1748.
The war began when the French East India Company captured the English East India Company’s fort at Madras. The English responded by capturing the French East India Company’s fort at Pondicherry. The war ended with the signing of the Treaty of Aix-la-Chapelle in 1748, which restored the status quo ante bellum.
The First Carnatic War was a significant event in the history of the Indian subcontinent. It marked the beginning of the rivalry between the French and the English East India Companies, which would eventually lead to the British conquest of India.
The other options are incorrect because they do not correspond to the dates of the First Carnatic War.
