Option 1 (1930) is the correct answer. On 26th January 1930, the Indian National Congress declared India`s independence from British rule. This important event, known as the Declaration of Independence or Purna Swaraj, marked a significant milestone in India`s freedom struggle. It was a symbolic declaration, as it marked the beginning of the demand for complete independence from foreign rule. This date, 26th January, was later chosen as the date for the adoption of the Indian Constitution in 1950, making it India`s Republic Day. However, it is important to note that India officially gained independence from British rule on 15th August 1947.
