Answer:
C. the demand curve for SUPs will shift to the right
Step-by-step explanation:
If buyers today become more willing and able to purchase larger quantities of SUPs at each price this will cause an increase of demand. In the demand and supply graph, each point of the demand curve (quantity, price) will move to the right (more quantity at each price), causing that the demand curve shifts to the right. It is not a movement along the demand curve because this happens when only price or quantity demanded changes, in this case, power to purchase changed, then it is a shift.
