Final answer:
A change in the price of good X causes a movement along the demand curve, not a shift. Changes in prices of complementary goods, consumer tastes and preferences, and consumer income will shift the demand curve.
Step-by-step explanation:
Of the options provided, a change in the price of good X will not cause a shift in the demand curve for good X. Instead, a change in the price of good X will cause a movement along the demand curve, not a shift of the curve. A shift in the demand curve would be due to a change in the price of a complementary good, a change in consumer tastes and preferences for good X, or an increase in consumer income, which can either increase or decrease the demand for good X depending on whether it is a normal or inferior good.
