Correct option is B
Ahmad Yadgar was a historian and chronicler of the sixteenth century who documented the political landscape of northern India during the late Delhi Sultanate period. The Sayyid dynasty (1414–1451) was the fourth dynasty to rule the Delhi Sultanate and was relatively short-lived and less powerful compared to its predecessors. Ala al-Din Alam Shah was its last ruler, and his reign marked the waning influence of the dynasty. Yadgar’s account helps us understand the limited geographical control during Alam Shah’s rule, highlighting the gradual fragmentation and political instability in the region.
