Classifying the economy type using circular flow indicators

Steps:

• Identify government spending (6) as evidence of public sector involvement.
• Note exports (9) and imports (10) as indicators of international trade.
• Recognize saving (5) as a household withdrawal, confirming domestic flows.
• Conclude the economy includes government and foreign sectors based on these components.

Why C is correct:

• A mixed economy features government intervention (spending present); an open economy involves trade (exports and imports shown), matching the definition of both sectors in circular flow models.

Why the others are wrong:

• A: No tax revenue data provided to compare with spending for surplus.
• B: While imports exceed exports, this is a specific outcome, not the broadest conclusion from all components.
• D: Equilibrium requires full balance of injections and withdrawals, but investment and taxes are absent, so unverifiable.

Final answer: C
