Qutub-ud-din Aibak founded which of the following dynasties?

Slave Dynasty

The correct answer is Option4- Slave Dynasty

Qutub-ud-din Aibak founded the Slave Dynasty.

The Slave Dynasty was the first dynasty of the Delhi Sultanate, which ruled over North India from the 13th to the 16th centuries. The dynasty was founded by Qutb-ud-din Aibak, a former slave of the Ghurid ruler Muhammad Ghori. Qutb-ud-din Aibak became the governor of the Ghurid possessions in India after Ghori's death in 1206, and he declared himself Sultan of Delhi in the same year.

The Slave Dynasty ruled over a large territory, which included parts of present-day India, Pakistan, and Bangladesh. The dynasty was known for its strong military and its efficient administration. The Slave Dynasty also produced some of the most notable rulers of Indian history, including Iltutmish, Balban, and Alauddin Khalji.

The Slave Dynasty came to an end in 1290, when it was overthrown by the Khilji Dynasty. However, the Slave Dynasty played an important role in the development of the Delhi Sultanate and in the spread of Islam in India.
