Four resolutions were passed at the famous Calcutta session of Indian National Congress in 1906. The question of either retention OR of rejection of these four resolutions became the cause of a split in Congress at the next Congress session held in Surat in 1907. Which one of the following was not one of those resolutions?

1. The 1906 Calcutta session of the Indian National Congress passed four key resolutions: Swaraj (Self-Government), Swadeshi, Boycott, and National education. 2. Disagreements over these specific four resolutions were the primary cause of the split in Congress at Surat in 1907. 3. Options (2) Boycott, (3) National education, and (4) Swadeshi represent three of these four key resolutions. 4. Option (1) Annulment of partition of Bengal, while a major demand arising from the political context, was not one of the specific four programmatic resolutions whose interpretation led directly to the split. 5. Therefore, the correct answer to the question "Which one of the following was not one of those resolutions?" is (1) Annulment of partition of Bengal.
