The correct answer is (c), Bahadur Shah.
Bahadur Shah was the ruler of Gujarat from 1526 to 1537. He was a powerful and ambitious ruler who expanded the Gujarati empire. However, he was also a reckless and impulsive ruler who made several mistakes, including the surrender of Diu to the Portuguese in 1535.
Diu was a strategically important port city that controlled the trade routes between India and the Middle East. The Portuguese had been trying to capture Diu for many years, and they finally succeeded in 1535 after a long siege. The surrender of Diu was a major blow to the Gujarati empire, and it marked the beginning of the decline of Gujarati power.
Ahmad Shah was the ruler of Gujarat from 1411 to 1442. He was a successful ruler who expanded the Gujarati empire and made it one of the most powerful kingdoms in India. However, he did not surrender Diu to the Portuguese.
Mahmud Begarha was the ruler of Gujarat from 1451 to 1511. He was a powerful and successful ruler who expanded the Gujarati empire and made it one of the most powerful kingdoms in India. However, he did not surrender Diu to the Portuguese.
Muhammad Shah was the ruler of Gujarat from 1537 to 1554. He was a weak and incompetent ruler who was unable to stop the decline of the Gujarati empire. He did not surrender Diu to the Portuguese, but he was unable to prevent the Portuguese from taking control of the city.
