It was during the reign of Muhammad bin Tughluq that Taimur occupied Multan and crossed the Indus.<br/>3. It was during the reign of Deva Raya II of Vijayanagara Empire that Vasco da Gama reached the coast of Kerala.<br/><br/>Which of the statements given above is/are correct?

1. Correct. Chengiz Khan reached the Indus in 1221 CE while pursuing Jalal al-Din Mangburni, and this was during the reign of Iltutmish.

2. Incorrect. Taimur invaded India in 1398 CE, occupying Multan and crossing the Indus during the reign of Nasir-ud-Din Mahmud Tughluq, not Muhammad bin Tughluq (who died in 1351).

3. Incorrect. Vasco da Gama reached Calicut in 1498 CE, but Deva Raya II ruled Vijayanagara in the early-mid 15th century; in 1498, the ruler was from the later Tuluva/Saluva transition period, not Deva Raya II.

Therefore, only Statement 1 is correct.
