Coalition politics, in effect, has tendency to grow in?
a) Bi-party System
b) Multi-party System
c) Single-party System
d) None of the above

The correct answer is B. Multi-party system.

Explanation:

In politics, a coalition is a temporary alliance of political parties, political groupings and parliamentary groups.   In many nations, parties form coalitions to form a stable government. This is necessary when - as is often the case in political systems with proportional representation - one party or parliamentary group alone does not have the absolute majority required to govern. Coalitions, however, do not necessarily have to have parliamentary majorities; minority governments based on coalitions are also common in some political systems.
