Consider the following statements : 1. It was during the reign of Iltutmish that Chengiz Khan reached the Indus in pursuit of the fugitive Khwarezm prince. 2. It was during the reign of Muhammad bin Tughluq that Taimur occupied Multan and crossed the Indus. 3. It was during the reign of Deva Raya II of Vijayanagara Empire that Vasco da Gama reached the coast of Kerala. Which of the statements given above is/are correct?

1. Statement 1 is correct. Chengiz Khan reached the banks of the Indus River around 1221 CE while pursuing Jalal al-Din Mangburni, the fugitive Khwarezm prince. This event occurred during the reign of Shamsuddin Iltutmish (1211-1236 CE), the Sultan of Delhi. 2. Statement 2 is incorrect. Taimur (Timur) invaded India and sacked Delhi in 1398 CE. At that time, the ruler of the Delhi Sultanate was Nasir-ud-Din Mahmud Shah Tughluq, not Muhammad bin Tughluq, whose reign ended in 1351 CE. 3. Statement 3 is incorrect. Vasco da Gama reached the coast of Kerala (Calicut) in 1498 CE. The reign of Deva Raya II of the Vijayanagara Empire was from 1422 to 1446 CE. Therefore, Vasco da Gama arrived significantly later, during the Saluva dynasty's rule in Vijayanagara.
