Step 1: Analyze the question The question asks which party system commonly produces a coalition government.

Step 2: Explain the concept A coalition government is formed when two or more political parties join together to govern. This usually happens when no single party wins a clear majority of seats in the legislature.

Step 3: Examine each option

• A. Two-party system: Two dominant parties usually compete (e.g., the USA, the UK historically). One of them normally wins an outright majority, so coalitions are rare.
• B. Multi-party system: Many parties compete and share seats. Often none of them gets a majority, so they must form alliances to govern (e.g., Israel, Netherlands, and Nigeria's First Republic, when the NPC and NCNC formed a coalition). Coalitions are common here.
• C. One-party system: Only one party is allowed, so there is nobody to form a coalition with.
• D. Non-party system: There are no parties at all, so a coalition of parties is impossible.

Step 4: Answer The correct answer is B. multi-party system.
