On which of the following dates, Constituent Assembly of India adopted the National Flag?

The correct answer is C) 22 July, 1947. On this day Jawaharlal Nehru moved the resolution in the Constituent Assembly adopting the tricolour as the National Flag. The design has saffron, white and green horizontal bands with the Ashoka Chakra in navy blue at the centre, replacing the charkha of the Congress flag. The Constituent Assembly's decision on the flag was taken on this date, well before the Constitution came into force on 26 January 1950.

Why the others are wrong:

• A (22 January, 1950): No flag decision was taken on this date. It falls in the final phase of the Assembly's work, just before the Constitution was adopted.
• B (24 January, 1950): On this date the Assembly formally adopted the National Anthem, Jana Gana Mana, and related national symbols were settled. The flag had already been decided in 1947.
• D (22 July, 1948): Right date, wrong year. The adoption happened in 1947.

Core concept: national symbols under the Constitution and the Flag Code. The Flag Code of India, 2002, later consolidated the rules on display and use of the flag, which is a useful Mains point on symbols and national identity.

Trap: Aspirants mix up the flag adoption (1947) with the Constitution's commencement and the anthem's adoption (1950), and pick the date that looks most 'constitutional'.
