Identifying the incorrect statement on direct government provision of flood control dams

Steps:

• Recall direct provision: Government directly supplies public or merit goods like flood control dams to address market failures.
• Evaluate A: Correct, as dams provide non-excludable, non-rivalrous public goods.
• Evaluate B: Correct, as flood control qualifies as a merit good supplied at cost to ensure provision.
• Evaluate C and D: C incorrectly implies unique forcing of opportunity cost; D is accurate as government action allocates resources.

Why C is correct:

• Opportunity cost applies to all economic decisions (definition: value of next-best alternative forgone), not uniquely "forced" by direct provision.

Why the others are wrong:

• A: Flood control dams are classic public goods, enabling government provision.
• B: Merit goods like flood control are supplied by government at cost to overcome underprovision.
• D: Direct provision exemplifies government resource allocation in mixed economies.

Final answer: C
