Answer:
a. Anywhere inside or on the production possibilities frontier.
Explanation:
In an economy, the allocative efficiency may be defined as the economic state where the production of various goods or services is aligned with the preferences with the consumers. Â
The allocative efficiency always materializes at the intersection of the supply curves and the demand curves.
On the [tex]\text{equilibrium point,}[/tex] the price for a supply [tex]\text{exactly matches}[/tex] with the demand for the product [tex]\text{for that supply}[/tex] at that price, and thus all the products are sold.
It occurs anywhere on the production possibilities frontier or on the inside of the frontier.
Therefore, the correct option is (a).
