The provided answer is incorrect. The question pertains to the historical event of the resignation of Congress ministries in the seven provinces of India in 1939.

Option 1 suggests that the Congress could not form ministries in the other four provinces. This isn`t the reason because the Congress had already formed ministries in seven provinces.

Option 2 refers to the emergence of a `left wing` in the Congress which made the working of the ministries impossible. However, this isn`t the cause as there were no such hindrances by a `left wing` leading to the resignation.

Option 3 indicates widespread communal disturbances in their provinces as the reason, but this was not the main cause of their resignation during this time.

The actual reason for their resignation was the declaration of war by Britain against Germany during World War II, without consulting Indian leaders - a fact not reflected in any of the options.

Alert - correct answer should be: “None of these. The ministries resigned because Britain declared war on Germany without consulting the Indian leaders.”
