Chenghiz Khan, although he was a prominent Mongol leader and known for his invasions across Asia and Europe, never crossed the Indus River to attack India. His empire did, however, lay the groundwork for future Mongolian invasions of India.

Tair Bahadur, Abdullah, and Qutlugh Khwaja are less known, but according to history, they crossed the Indus to invade India. Tair Bahadur and Abdullah were Mongol commanders who carried out invasions into Northern India. Qutlugh Khwaja was a Chagatai Mongol leader, who also invaded India.

So, in the given options, Chenghiz Khan is the only Mongol leader who did not cross the Indus to attack India, making option 1 the correct answer.
