Market Economy Institutions

Steps:

• Define market economy as a system driven by private ownership, competition, and profit motives.
• Review choices for pairs consisting of private sector entities that facilitate trade and finance.
• Eliminate options with public or non-profit elements not central to market operations.
• Confirm the pair with both competitive, privately run institutions.

Why B is correct:

• Monopolies and commercial banks are private enterprises; per economic theory, banks provide capital allocation via markets, while monopolies arise from unregulated competition in market economies.

Why the others are wrong:

• A: Local government is public sector; charities are non-profit, not profit-driven market players.
• C: Nationalised industries are state-owned, contradicting private ownership in market economies.
• D: Public corporations are government-controlled, not privately operated market institutions.

Final answer: B
