The correct answer is option 2, which states that statements 1 and 2 are correct.

Let`s dissect each option to understand why:

Option 1: "1 only" - This option states that only statement 1 is correct. Statement 1 says that the Quit India Movement of 1942 was massive in character. This is true because the movement saw wide-scale participation from various sections of society, including students, workers, farmers, and professionals.

Option 2: "1 and 2" - This option states that both statements 1 and 2 are correct. Statement 2 says that one of the unique features of the movement was the participation of communists at the local level, defying the official stand of the Communist Party. This is true because even though the Communist Party had initially opposed the movement, many individual communist leaders and workers supported it at the grassroots level.

Option 3: "2 only" - This option states that only statement 2 is correct. As discussed earlier, statement 2 is indeed correct.

Option 4: "1 and 3" - This option states that both statements 1 and 3 are correct. However, statement 3, which says that the movement was completely non-violent, is not accurate
