Price increase causes movement along the supply curve, but exact quantity change requires extrapolation not matching choices Steps:

• Identify supply at $12: 160 units from table.
• Observe pattern: supply increases by 40 units per $2 price rise (e.g.,$10 to $12: 120 to 160).
• Extrapolate to $18: +$6 from $12 implies +120 units (3 intervals × 40), so supply = 280 units.
• Note: table ends at $16 (240 units); no direct data for$18, and 120-unit extension doesn't match any choice.

Why C is correct:

• Not applicable; no option fully aligns with law of supply (price ↑ → quantity supplied ↑ along curve).

Why the others are wrong:

• A: "Contract" implies decrease, but price ↑ causes extension (increase); movement up is right but quantity wrong.
• B: "Contract by 200" and inward shift contradict price ↑ effect; shifts require non-price factors.
• D: "Extend by 200" overstates extrapolated increase (actual +120); outward shift incorrect for price-only change.
