Any changes in power sharing arrangement can be done by _________________.
A. Simple majority in both the houses of parliament
B. Clear majority in both the houses of parliament
C. Two-third majority in both the Houses of Parliament and passed by at least half of the total state legislatures
D. None of these

Hint: Consociationalism is a procedure of power-sharing in a democracy. Political researchers describe a consociation state as one which has foremost internal separations along cultural, religious, or verbal lines, with none of the separations big enough to form a majority group, but which remains steady owing to discussion amid the leaders of these groups.

Complete answer:
The sharing of power between the Union Government and the State governments is rudimentary to the assembly of the Constitution. It is not stress-free to make variations to this power-sharing procedure. The Parliament cannot on its own alter this procedure. Any alteration to it has to be first approved by both the Houses of Parliament with more than two-thirds majority. Then it has to be sanctioned by the legislatures of more than half of the overall States. In case of any disagreement about the separation of authorities, the High Courts and the Supreme Court can make a pronouncement. Consociationalism was deliberated in theoretical terms by the political researcher Arend Lijphart. Though, Lijphart has specified that he had "just revealed what political consultants had recurrently – and autonomously of both theoretical connoisseurs and one another – devised years prior". John McGarry and Brendan O'Leary track consociationalism back to 1917, when it was initially exercised in the Netherlands.

Thus, option (C) is correct.

Note: Consociation was initially deliberated in the 17th century New England Confederation. It defined the inter-association and collaboration of the contributor self-governing Congregational churches of the numerous colonial communities of the Massachusetts Bay Colony. These were authorized in the city legislature and magistrate. It was discussed at the Boston Synod of 1662. This was when the Episcopalian Act of Uniformity 1662 was being familiarized in England.
