Answer:
The correct answer is c.
Step-by-step explanation:
Since the point the text is mentioning is above the equilibrium point, we know that the Demand is lower than it should be, while supply is bigger.
In order to increase the demand and lower the supply, we need to decrease the price to the equilibrium price. This will increase the demand and lower the supply making them intersect and reach the equilibrium point, a point that the invisible hand is influencing.
