Answer:
d. create a more fair distribution of income
Explanation:
The market forces sometimes do not allocate resources efficiently, therefore, the government sometimes intervenes in order to promote efficiency and create a more fair distribution of income.
For example, if the price for which market forces allocate for a good is too low, the government can intervene by setting a price floor.
Also, if the price of a good is too high, government can enact a price ceiling.
This ensures that the income of both producers and consumers are more fairly distributed.
Also, if a monopoly is setting the price of its goods too high, the government can regulate the activities of the monopoly to create a more fair distribution of income.
