In Calcutta, the first National Flag of India was hoisted on:

Question

Accepted Answer

The correct option is 2:
The correct answer is August 7, 1906. This date marks a watershed moment in the history of the Indian National Movement, as it was on this day that the first unofficial national flag, famously known as the 'Calcutta Flag' or the 'Vande Mataram Flag', was hoisted. This historic event took place at Parsi Bagan Square (now Greer Park) in Calcutta. The flag's unfurling was a powerful, symbolic act of protest led by the nationalist leaders against the British policy of partitioning Bengal and was directly linked to the Swadeshi movement, providing a visual symbol of national unity and resistance well before the officially adopted Tricolour of 1947.

The incorrect option is 1:
January 18, 1948 is incorrect because by this time, India had already achieved independence. The modern Tricolour was officially adopted by the Constituent Assembly on July 22, 1947, and unfurled on August 15, 1947. This date, falling well into the post-independence period, is chronologically separate from the early nationalist activities where the first flag was conceptualized and hoisted in Calcutta. Therefore, 1948 represents the culmination, not the starting point, of the journey for a national flag.

The incorrect option is 3:
July 18, 1930 is incorrect as it refers to a time much later in the freedom struggle. By 1930, the Indian National Congress was in the process of resolving to adopt the Swaraj Flag, which prominently featured the spinning wheel (Charkha) and was associated with Mahatma Gandhi's non-violent movement and the demand for Purna Swaraj (Complete Self-Rule). The Calcutta Flag of 1906 is a historically distinct symbol that precedes this period by nearly a quarter of a century, placing it in an entirely different political context.

The incorrect option is 4:
May 24, 1920 is also incorrect because the first flag was unfurled in 1906. The year 1920 is associated with the launch of the Non-Cooperation Movement under Mahatma Gandhi, which initiated a new phase of the freedom struggle. While this period saw the emergence of a new flag proposal (the original red and green with a Charkha), it was 14 years after the Calcutta Flag had already served as the first public symbol of a unified Indian nation.
