Which one of the following pairs is not correctly matched ?

The transfer of India's capital from Calcutta to Delhi is incorrectly matched with 1909. Historical records confirm that the decision to shift the capital was announced by King George V during the Delhi Durbar in December 1911 [c2][t1]. The actual transfer took place in 1912 [t1][t3]. The other pairs are historically accurate: the Partition of Bengal was implemented in 1905 under Lord Curzon [c3][t3]; the All-India Muslim League was founded in Dacca on December 30, 1906 [c5][t6]; and the Surat Split, which saw the Indian National Congress divide into Moderates and Extremists, occurred in 1907 [t1]. The 1911 announcement also included the annulment of the Bengal partition as a measure to curb revolutionary activities and appease political sentiments [c1].
