The correct option is B Muhammad-bin-Tughlaq
In the fourteenth century, the Delhi sultanate was very powerful. Rulers like Alauddin Khilji and Mohammad-bin-Tughlaq, in order to assert their dominance throughout India, ventured into south India to take over parts of the region. However, the end of Mohammad-bin-Tughlaq's reign marked the beginning of the decline of the Delhi sultanate. It also led to the disintegration of the Tughlaq empire.
