Explanation: The Delhi Sultanate was a significant period in Indian history, marked by the rule of various dynasties, including the Tughlaq Dynasty. The Tughlaq Dynasty, which ruled from 1320 to 1414, was a crucial phase in the Delhi Sultanate's history. It was founded by Ghiyasuddin Tughlaq, who was succeeded by his son Muhammad Bin Tughlaq, a well-known ruler known for his ambitious but often unsuccessful administrative reforms.
Khizr Khan, who succeeded Muhammad Bin Tughlaq, was not a direct descendant but a governor who took over the throne. He ruled from 1320 to 1321 and was succeeded by his son, Mubarak Shah. Mubarak Shah's reign was short-lived, lasting only a year, but he is historically significant as the immediate successor to Khizr Khan.
Understanding the succession within the Tughlaq Dynasty is essential for comprehending the political and administrative changes that occurred during this period. The Tughlaq Dynasty was marked by both expansion and decline, with Muhammad Bin Tughlaq's reign being particularly notable for its ambitious policies and subsequent challenges.
It is important to distinguish between the different rulers and their roles within the Delhi Sultanate. For instance, Ghiyasuddin Balban, mentioned in Option B, was a ruler of the Mamluk Dynasty, which preceded the Tughlaq Dynasty. Similarly, Sikandar Lodi, mentioned in Option D, was a ruler of the Lodi Dynasty, which came much later and is not related to the succession of Khizr Khan.
In summary, the correct answer is Mubarak Shah, who succeeded Khizr Khan as the Sultan of Delhi. This succession is a key part of the historical narrative of the Tughlaq Dynasty and the broader context of the Delhi Sultanate. Understanding these historical details is crucial for students studying Indian history, particularly for competitive examinations that focus on historical chronology and dynastic succession.
