The representatives of each State in the Council of States are elected by the elected members of the Legislative Assembly of the State. This is done in accordance with the system of proportional representation by means of the single transferable vote.
Option 1 provides the correct explanation. The system of proportional representation means that the number of representatives allocated to each State is proportional to its population. This allows for fair representation of all States in the Council of States.
Option 2 is incorrect because it suggests that the representatives are elected by both the Legislative Assembly and Legislative Council of the State.
Option 3 is incorrect because it suggests that the representatives are elected by the House of People from the State, which is not the case.
Option 4 is incorrect because it provides information about the composition of the Council of States, but does not explain how the representatives are elected.
In conclusion, the representatives of each State in the Council of States are elected by the elected members of the Legislative Assembly of the State, using the system of proportional representation by means of the single transferable vote.
