The correct answer is option 2, Pondicherry. Pondicherry, also known as Puducherry, was an important French possession in India. It was a colonial settlement established by the French in the 17th century. During the colonization period, Pondicherry served as the capital of French India. It had a significant French influence in terms of its architecture, culture, and lifestyle. Today, Pondicherry is a popular tourist destination known for its French colonial heritage, picturesque beaches, and spiritual retreats. Goa, mentioned in option 1, was a Portuguese possession in India, not French. Surat and Ahmedabad, mentioned in options 3 and 4, were important cities in India but not French possessions.
