Explanation: Delhi, the capital city of India, is renowned for its rich historical and cultural heritage. The city is home to numerous historical sites that reflect its diverse past and the various empires that have ruled over it. Among these sites, India Gate, Qutub Minar, and Jantar Mantar stand out as significant landmarks.
India Gate, located in the heart of New Delhi, is a war memorial that commemorates the soldiers who died in the First World War and the Third Anglo-Afghan War. It was designed by Sir Edwin Lutyens and completed in 1931. The monument is a blend of Indian and Western architectural styles and is a prominent symbol of Delhi's colonial history.
Qutub Minar, located in South Delhi, is a UNESCO World Heritage Site and one of the tallest minarets in the world. It was built in the 12th century by Qutbuddin Aibak, the first Muslim ruler of Delhi, and completed by his successor Iltutmish. The minaret is a symbol of Delhi's rich Islamic heritage and is surrounded by other historical structures such as the Quwwat-ul-Islam Mosque and the Iron Pillar. The Qutub Minar complex is a testament to the architectural and artistic achievements of the Delhi Sultanate.
Jantar Mantar, located in Connaught Place, is an astronomical observatory built in the early 18th century by Maharaja Jai Singh II. The observatory consists of 13 architectural astronomy instruments and is a significant historical and scientific landmark. It was built to observe the movements of celestial bodies and to calculate time, eclipses, and planetary positions. The Jantar Mantar is a unique example of the scientific and mathematical knowledge of the time and is one of the five such observatories built by Jai Singh II in different parts of India.

Therefore, the correct answer is (D) All of them, as all three options are indeed historical sites in Delhi.
