With reference to the Indian freedom struggle, which one of the following statements is not correct?

Statement (3) is incorrect. The All-India Muslim League (formed in 1906) did not vehemently oppose separate electorates; on the contrary, Muslim leaders including those who initiated the League sought separate representation and later secured separate electorates under reforms, reflecting a pro-British stance rather than opposition to communal measures [3]. Other statements are supported by sources: Hakim Ajmal Khan was an early founder/leader associated with the All-India Muslim League and later with nationalist causes [1]; Sir Syed Ahmad Khan was a loyalist who favored cooperation with the British and was not aligned with the founding outlook of the Congress [2]; Maulana Barkatullah and Maulana Obaidullah Sindhi were involved in the Provisional Government of India established at Kabul in 1915 [4].
