The Congress ministries resigned in 1939 primarily in response to the failure of the British government to consult Indian leaders regarding the involvement of India in World War II. The Indian National Congress believed that the decision to enter the war was made unilaterally, undermining India's aspirations for self-governance and sovereignty. This act of resignation was a significant step in the ongoing struggle for independence, highlighting the Congress's commitment to self-determination and their opposition to British imperialism, rather than any specific statements related to economic or social policies, thus making the correct option "None of the statements (a), (b) and (c) given above is correct."
