The correct answer is B. 1510.
The Portuguese defeated the Bijapur sultan Yousuf Adil Shah in the Battle of Diu on February 3, 1510. The battle was fought at the port city of Diu, which is located on the western coast of India. The Portuguese were led by Afonso de Albuquerque, while the Bijapur army was led by Yousuf Adil Shah himself. The battle was a decisive victory for the Portuguese, and it marked the beginning of the Portuguese Empire in India.
The Portuguese had been trying to establish a foothold in India for several years prior to the Battle of Diu. They had already established a number of trading posts along the coast, but they had been unable to make any significant inroads into the interior of the country. The Battle of Diu changed all of that. After their victory, the Portuguese were able to establish a number of forts and trading posts along the coast, and they began to exert a significant influence on the politics of the region.
The Battle of Diu was a major turning point in the history of India. It marked the beginning of the Portuguese Empire in India, and it had a profound impact on the political and economic development of the region.

Option C is incorrect because the Battle of Diu was fought in 1510, not 1517.
