Rulers

**Statement 1 is incorrect.** The first Mongol raid into India actually occurred in 1221 during the reign of Iltutmish of the Delhi Sultanate. Jalal-ud-din Khalji ruled much later (1296-1298 CE). **Statement 2 is correct.** A major Mongol invasion led by Kadar did indeed reach Delhi and lay siege to the city during the reign of Ala-ud-din Khalji (1296-1316 CE). However, his forces successfully repelled the invaders. **Statement 3 is incorrect.** Muhammad-bin-Tughlaq faced Mongol invasions during his reign, but there is no historical evidence to suggest that he temporarily lost portions of the northwest of his kingdom to the Mongols. Therefore, the correct answer is "2 only".
