Explanation: The Qutub Minar, located in Delhi, is one of the most iconic and historically significant monuments in India. It stands as a testament to the architectural prowess and historical evolution of the Delhi Sultanate. The construction of the Qutub Minar began under the reign of Qutbuddin Aibak, the first Sultan of Delhi, in the early 13th century. The initial purpose of the minaret was to serve as a victory tower and a call-to-prayer tower for the nearby Quwwat-ul-Islam Mosque.
The construction of the Qutub Minar was not completed in one go but was a process that spanned several decades and involved multiple rulers. Qutbuddin Aibak laid the foundation and started the construction, but he did not complete it. Iltutmish, who succeeded Aibak, continued the construction and completed the first three storeys of the minaret. The fourth storey was added by Alauddin Khilji in the late 13th century.
The fifth storey, which is the focus of this question, was added by Firoz Shah Tughlaq, who ruled from 1351 to 1388. Firoz Shah Tughlaq was a significant ruler of the Tughlaq dynasty and is known for his extensive architectural projects and renovations. The addition of the fifth storey to the Qutub Minar is a notable contribution to the monument's structure and historical significance.
Understanding the construction history of the Qutub Minar is crucial for comprehending the architectural and historical evolution of Delhi during the Delhi Sultanate period. Each ruler who contributed to the minaret's construction left their mark, reflecting the changing styles and priorities of the time. The Qutub Minar, with its five storeys, stands as a symbol of the architectural and cultural heritage of Delhi, showcasing the contributions of various rulers over several centuries.
In summary, the fifth storey of the Qutub Minar was built by Firoz Shah Tughlaq, making option B the correct answer. This addition is a significant part of the minaret's history and highlights the architectural contributions of the Tughlaq dynasty to Delhi's historical landscape.
