The correct answer is:
To allocate scarce goods and resources, a market economy uses price rationing. this means that individuals will get the goods and services if they have the ability to pay.
Market economy is based on the decisions reached by the interactions of economic agents (households, firms and public sector) in the markets, whose mechanisms match the quantity of each good or service demanded by consumers with the quantity manufactured and offered by producers, at a certain price level. Those consumers who are able to afford the market price will obtain the product, this is why the system can be denominated price rationing.
