Four resolutions were passed at the famous Calcutta session of Indian National Congress in 1906. The 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?

The Calcutta (1906) Congress adopted a programme that explicitly endorsed Swadeshi, Boycott and National Education, and even introduced the term 'Swaraj' for the first time; these formed the contentious set of resolutions whose retention or rejection led to the Surat split in 1907 [1]. Historical accounts of the 1906 proceedings describe a resolution supporting the programme of swadeshi, boycott and national education, and show that the split revolved around these items when Moderates sought to drop them at the next session [2]. Opposition to the Partition of Bengal was a major issue in 1905 and earlier Congress sessions, but it was not listed among the four specific resolutions at Calcutta in 1906, so "Annulment of partition of Bengal" was not one of those four resolutions [3].
