Option 1 states that provisions for citizenship, elections, provisional parliament, and fundamental rights came into effect on 26th November, 1949. Option 2 states that provisions for citizenship, elections, and provisional parliament came into effect on that date. Option 3 suggests that only provisions for citizenship and provisional parliament came into effect. Option 4 states that only provisions for citizenship and elections came into effect.

The correct answer is option 2 because it accurately states that provisions for citizenship, elections, and provisional parliament came into effect on 26th November, 1949. However, it is important to note that fundamental rights also came into effect on this date, which is not mentioned in any of the options. So, the correct answer should mention all four provisions: citizenship, elections, provisional parliament, and fundamental rights.

Alert - correct answer should be option 1: 1. Citizenship, 2. Elections, 3. Provisional Parliament, and 4. Fundamental Rights.
