The correct answer is option 4, Karnataka. The Non-Cooperation Movement was a significant phase in the Indian independence movement, led by Mahatma Gandhi. It aimed to resist British colonial rule through nonviolent means such as boycotts and protests.
During this movement, South India witnessed widespread participation and support, except for Karnataka. The linguistic regions in South India include Kerala, Tamil Nadu, Andhra Pradesh, and Karnataka. While Kerala, Tamil Nadu, and Andhra Pradesh actively participated in the Non-Cooperation Movement, Karnataka remained largely unaffected.
It is important to note that the provided answer is generally correct, assuming that the Non-Cooperation Movement did not have a significant impact in Karnataka. However, it is essential to consider that historical events can be complex, and there may have been pockets of resistance or participation in Karnataka during this movement.
