Who was fascinated with the trading conditions in India, and compared India to Iran and the Ottoman Empire?

Jean-Baptiste Tavernier

The correct answer is Option 1 - Jean-Baptiste Tavernier

One of the most famous was the French jeweller Jean-Baptiste Tavernier, who travelled to India at least six times. He was particularly fascinated with the trading conditions in India, and compared India to Iran and the Ottoman empire. Some of these travellers, like the Italian doctor Manucci, never returned to Europe, and settled down in India.
