Correct option is C
The Qutb Minar and Red Fort are both recognized as UNESCO World Heritage Sites due to their historical and architectural significance.
The Qutb Minar, located in Delhi, is the tallest brick minaret in the world and is part of the Qutb Complex, which was declared a World Heritage Site in 1993.
The Red Fort, also in Delhi, was designated a UNESCO World Heritage Site in 2007. It was the main residence of the Mughal emperors for around 200 years and remains a symbol of India's rich history and cultural heritage.
However, the India Gate is not a UNESCO World Heritage Site. It is a war memorial built in 1931 in honor of the Indian soldiers who died during World War I and the Third Anglo-Afghan War. While it is an iconic structure and a popular tourist destination, it does not have the historical or architectural significance required for UNESCO World Heritage designation.
