The question asks about the significance of the Lahore session of the Indian National Congress held in 1929. Understanding this session is crucial for studying the history of the Indian independence movement.

Let's examine the options provided and relate them to the historical events of the Indian National Congress, particularly in 1929.

Understanding the Significance of the Lahore Session 1929

The Lahore session of 1929 was a pivotal moment in India's freedom struggle. It was presided over by Jawaharlal Nehru. The mood of the nation was increasingly impatient with the slow pace of constitutional reforms offered by the British government.

Analysis of Options for Lahore Session 1929 Significance

1. it passed the resolution to demand Poorna Swaraj.

   This option refers to the demand for Poorna Swaraj, meaning complete independence. The Lahore session of 1929 is historically recognized as the session where the Indian National Congress officially declared Poorna Swaraj as its ultimate goal, abandoning the earlier demand for Dominion Status.

2. it passed the resolution to start the Rowlatt Satyagraha.

   The Rowlatt Satyagraha was launched in 1919 by Mahatma Gandhi against the Rowlatt Act. This event predates the Lahore session of 1929 by a decade and is unrelated to its primary significance.

3. it passed the resolution to hold civil services examination in India.

   The demand for holding civil services examinations in India simultaneously with England was an older demand of the nationalist movement, dating back to the late 19th century. While important, it was not the defining resolution of the Lahore session of 1929.

4. it passed the resolution to boycott provincial elections.

   The decision to boycott elections or councils was taken by the Congress at various points depending on the political situation, such as during the Non-Cooperation Movement (early 1920s) or in response to specific government actions. However, the main resolution and significance of the Lahore session 1929 was the declaration of Poorna Swaraj.

Based on historical facts, the most significant outcome of the Lahore session of 1929 was the formal declaration of Poorna Swaraj (complete independence) as the objective of the Indian National Congress.

Key Decisions at the Lahore Session 1929

• It was decided that 26th January should be observed as "Poorna Swaraj Day" every year.
• The Congress authorized the Working Committee to launch a Civil Disobedience Movement.

Additional Information on Poorna Swaraj and 1929 Session

Following the Lahore session of 1929, the Indian National Congress called upon the people of India to observe 26th January as Independence Day (later known as Poorna Swaraj Day). On this day, public meetings were held across the country, and the pledge of independence was read out. This tradition continued until India achieved independence in 1947. The date 26th January was later chosen as the date for the Indian Republic Day to commemorate the significance of the Poorna Swaraj declaration.

The passage of the Poorna Swaraj resolution was a bold step that reflected the growing impatience and resolve of the Indian people and their leaders to achieve full freedom from British rule. It marked a turning point in the freedom struggle, clearly defining the objective that the nationalist movement would now strive for.
