The correct answer is: A. 1531 AD
Nino da Cunha was the Portuguese Governor of India from 1529 to 1532. In 1531, he transferred the capital of Portuguese India from Cochin to Goa. This was a significant event in the history of Portuguese India, as it marked the beginning of Goa’s rise to prominence as the center of Portuguese power in the region.
There are several reasons why Nino da Cunha decided to transfer the capital to Goa. First, Cochin was located in a relatively vulnerable position, as it was surrounded by hostile Hindu kingdoms. Goa, on the other hand, was located on a peninsula that was more easily defensible. Second, Goa was a more centrally located city, which made it easier to administer the Portuguese territories in India. Third, Goa had a natural harbor, which made it a more important trading center.
The transfer of the capital to Goa had a significant impact on the history of Portuguese India. It marked the beginning of Goa’s rise to prominence as the center of Portuguese power in the region. It also led to the development of Goa into a major trading center and cultural hub.
The other options are incorrect because they are not the year in which Nino da Cunha transferred the capital of Portuguese India from Cochin to Goa.
