Consider the following statement :
The three Movements of Gandhi were named variously as the Non-Cooperation Movement, the Civil Disobedience Movement and the Quit India Movement because :
1. Gandhi wanted to attract the Indian masses to his movement by giving it a different name each time.
2.when a movement failed, he did not want to use the same name for his new movement.
3. each movement was more rigorous than the previous one.
4. Gandhi prepared the masses slowly from non-cooperating in 1921 to telling the British to quit India in 1942.
Which of these statements are correct ?
