Explanation:

? Hindu Mahasabha was founded in 1915 with Madan Mohan Malviya as a founding leader along with others such as V.D Savarkar, Lala Lajpat Rai. The Sabha laid emphasis on Hindu solidarity and the need for social reform.
? While not supportive of British rule, the Mahasabha did not offer its full support to the nationalist movement, abstaining from participating in the Civil Disobedience movement of 1930 and the Quit India movement of 1942. Hence, statement 2 is not correct.
? Mahasabha was also opposed to Gandhi’s overtures to hold parleys with Muslim League president Muhammad Ali Jinnah and Congress’ efforts to integrate Muslims
? When in 1939, the Congress ministries resigned in protest against Viceroy Lord Linlithgow's action of declaring India to be a participant in the Second World War without consulting the Indian people Hindu Mahasabha joined hands with the Muslim League and other parties to form governments in Sindh, NWFP, and Bengal. Hence, statement 1 is correct.
