Which one of the following movements has contributed to a split in the Indian National Congress resulting in the emergence of 'moderates' and 'extremists'?

The Swadeshi Movement (1905) led to the 1907 Surat Split because Moderates and Extremists disagreed on whether to extend the boycott beyond Bengal and whether to use radical methods of agitation. While the Non-Cooperation Movement also caused internal friction, it resulted in the "Pro-changers" and "No-changers" divide (leading to the Swaraj Party) rather than the original Moderate-Extremist split. The core concept tested is the ideological evolution and internal power struggles of the Indian National Congress during the early 20th century.
