Statement 1 is correct because while most princely states eventually joined, some initially hesitated or were not represented in the Constituent Assembly at the beginning. For instance, Hyderabad did not send representatives until after Partition. Statement 2 is incorrect because the elections to the Constituent Assembly were indirect, based on the provincial assemblies, not direct elections. The franchise for these provincial elections was indeed limited. Statement 3 is correct. After the Indian Independence Act, 1947, the Constituent Assembly became a fully sovereign body and also functioned as the provisional Parliament (Dominion Legislature) until the first general elections in 1951-52. Statement 4 is correct. Some provisions of the Constitution, such as those relating to citizenship, elections, provisional parliament, and temporary and transitional provisions (Articles 5, 6, 7, 8, 9, 60, 324, 366, 367, 379, 380, 388, 391, 392, and 393) came into force on November 26, 1949, the date of its adoption, while the remaining provisions came into force on January 26, 1950.
