In the early Delhi Sultanate phase, Qutbuddin Aibak was the commander of whom?

Correct answer: Muhammad Ghori

The correct answer is B, Muhammad Ghori, also called Muhammad of Ghor. Qutbuddin Aibak began his career as a military commander and trusted slave-general of Muhammad Ghori in the late twelfth century. Aibak led campaigns in northern India on his master’s behalf and later became the ruler of the Delhi Sultanate after Ghori’s death in 1206. Babur and Akbar belonged to the much later Mughal period, while Sher Shah Suri ruled in the sixteenth century and belonged to a different Afghan dynasty. The chronological sequence is the key: Muhammad Ghori came first, Aibak served him, and Aibak later established the Mamluk or Slave dynasty in Delhi.
