In which of the following provinces was Congress unable to form a Ministry despite emerging as the single largest party in the provincial elections of 1937?

The correct answer is Option 1 , i.e Assam . As per the Government of India Act 1935, provincial elections were held in eleven provinces in 1936 - 37. Congress emerged the overall leader by winning 707 of the total 1585 seats. In Assam , it won 33 out of a total of 108 seats , thereby becoming the single largest party, though not enough to form a ministry. The leader of the Assam Valley Muslim Party, Sir Muhammad Sadulla then formed the government with Congress as part of the ruling coalition.
