Movement along the supply curve occurs due to a change in the price of the good itself. Therefore, an increase in the price of energy-efficient light bulbs would cause a movement along the supply curve from point a to point c. A decrease in the price of energy-efficient light bulbs (option A), an increase in the number of suppliers of energy-efficient light bulbs (option C), or a decrease in the price of ordinary light bulbs (option E) would all result in a shift in the supply curve, not a movement along it. Option B is irrelevant to the movement along the supply curve for energy-efficient light bulbs.
