Explanations:The Indian national flag, known as the Tricolour or Tiranga, is a symbol of the country's independence and unity. The flag was officially adopted by the Constituent Assembly of India on July 22, 1947, which is the correct answer to this question. This date is significant because it precedes India's independence from British rule on August 15, 1947, and the adoption of the Constitution on January 26, 1950.
The design of the Indian national flag was finalized by a committee headed by Dr. S. Radhakrishnan, which included representatives from different political parties and communities. The flag consists of three horizontal stripes of equal width: saffron (top), white (middle), and green (bottom). In the center of the white stripe is a navy blue wheel with 24 spokes, known as the Ashoka Chakra, which represents the eternal wheel of dharma (righteousness).
The saffron color symbolizes courage and sacrifice, the white color symbolizes purity and truth, and the green color symbolizes faith and fertility. The Ashoka Chakra represents the eternal wheel of dharma and the 24 spokes symbolize the 24 hours of the day, indicating that there is no distinction between day and night in the pursuit of truth and righteousness.
Understanding the historical context of the adoption of the national flag is important for students of Indian history and for those preparing for competitive examinations such as the UPSC, SSC, and other state-level examinations. The flag's adoption on July 22, 1947, is a significant event in the timeline of India's transition to independence and the formation of the modern Indian state.
