The correct option is C A coalition government
No one national party is able to secure on its own a majority in the Lok Sabha, until 2014. As a result, the national parties are compelled to form alliances with State parties. Since, 1996, nearly every one of the State parties have got an opportunity to be a part of one or the other national-level coalition government. This has contributed to the strengthening of federalism and democracy in our country.
