Answer:
The correct answer is option c.
Step-by-step explanation:
When people move to a previously unpopulated area, the quantity of both consumers as well producers will increase. This will create an increase in both the demand as well as the supply. Both the demand and the supply curve will move to the right.
This rightward shift in both the demand as well as supply curve will lead to an increase in equilibrium quantity. The change in equilibrium price will depend upon the extent of change in demand and supply.
