The correct option is B It was the response of the British against the launch of the 'Quit India Movement'.
The All India Congress Committee on 8th August, 1942, met at Bombay and passed the 'Quit India Resolution'. To respond, the British imprisoned Gandhi and the other prominent leaders of the Congress the day after, i.e. on 9th August, 1942. The common masses were not at all happy with this treatment meted out by the British. So they resisted by attacking police stations, post offices, railway stations, law court buildings, etc. Angry mobs cut telephone and telegraph wires in 3500 places.
