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?

Let's analyze each statement: 1. It was during the reign of Iltutmish that Chengiz Khan reached the Indus in pursuit of the fugitive Khwarezm prince: This statement is correct. In 1221 CE, the Mongol leader Chengiz Khan pursued Jalaluddin Mangabarni, the Khwarezm Shah's son, to the banks of the Indus River. At this time, Iltutmish was the Sultan of Delhi. Iltutmish prudently refused asylum to Jalaluddin, thereby saving his nascent Delhi Sultanate from the wrath of the Mongols. 2. It was during the reign of Muhammad bin Tughluq that Taimur occupied Multan and crossed the Indus: This statement is incorrect. Taimur (Timur) invaded India in 1398 CE. At that time, the Delhi Sultanate was ruled by Nasir-ud-din Mahmud Shah Tughlaq, who was the last ruler of the Tughlaq dynasty. Muhammad bin Tughluq's reign was much earlier (1325-1351 CE). 3. It was during the reign of Deva Raya II of Vijayanagara Empire that Vasco da Gama reached the coast of Kerala: This statement is incorrect. Vasco da Gama reached Calicut (Kerala) in 1498 CE. Deva Raya II of the Sangama dynasty ruled the Vijayanagara Empire from 1424 to 1446 CE. At the time of Vasco da Gama's arrival, the Vijayanagara Empire was under the rule of the Saluva Dynasty. Therefore, only statement 1 is correct.
