Demand Curve Shifts from Non-Price Determinants Steps:

• Identify that a change in demand from D1 to D2 refers to a shift in the demand curve, caused by factors other than coffee's price.
• Recall demand shifters: consumer income, tastes, prices of related goods, expectations, or population.
• Evaluate options: A and C affect related goods' prices or tastes toward substitutes; B affects production costs (supply shifter).
• Note ambiguity: Without a diagram showing if D2 is rightward (increase) or leftward (decrease), direction is unclear; D option missing.

Why B is correct:

• Not applicable; B shifts supply leftward due to higher costs (law of supply: higher input costs reduce quantity supplied at each price).

Why the others are wrong:

• A: Raises substitutes' prices, shifting coffee demand right (complements/substitutes price effect).
• C: Boosts tea demand, shifting coffee demand left as tea is a substitute.

Not enough information to select definitively without shift direction or full options.

Final answer: Not enough information.
