The correct options are
A Extension of federal principles to all the units of federation
C Ensuring greater power to local government
D Inclusion of women and minority groups
Most of the established democracies face the challenge of expansion. This involves applying the basic principle of democratic government across all the regions, different social groups, and various institutions. Ensuring greater power to local governments, extension of the federal principle to all the units of the federation, inclusion of women and minority groups, etc., fall under this challenge. This also means that less and fewer decisions should remain outside the arena of democratic control. Most countries including India and other democracies like the US face this challenge.
