Price mechanism functions in resource allocation Steps:

• Define price mechanism as the system where prices adjust to balance supply and demand, guiding economic decisions.
• List core functions: signaling resource needs, incentivizing production, and rationing scarcity.
• Compare each choice to these functions.
• Identify mismatch: maximizing consumer surplus is a market outcome, not a direct function.

Why C is correct:

• Consumer surplus maximization requires perfect competition without distortions, per welfare economics; price mechanism alone handles allocation but not surplus optimization.

Why the others are wrong:

• A: Prices rise with demand, signaling firms to allocate resources there.
• B: High prices incentivize firms to produce more, aligning supply with demand.
• D: Prices exclude low-value users, rationing limited resources to highest bidders.

Final answer: C
