An increase in consumer incomes would cause a shift in the demand curve for coffee to the right, as people can afford to purchase more coffee at each price level. This is represented by the shift from D₁ to D₂. The other options may affect the quantity demanded of coffee, but not the overall demand for coffee, and therefore would not cause a shift in the demand curve.
