A price floor is usually fixed
The correct answer is: A
Explanation
A price floor is typically fixed above the equilibrium price. By setting the price floor higher than the equilibrium, it creates a surplus or excess supply in the market. Producers are incentivized to increase their supply at the higher price, but consumers demand less at the inflated price. As a result, there is an imbalance in the market with a surplus of the product.
The presence of surpluses created by the price floor can lead to various issues such as increased storage costs, wasted resources, and potential government interventions to address the surplus.
