Answer:
The economic system with the widest selection of consumer goods is the market economy.
Step-by-step explanation:
The market economy is an economic system in which all of the business is private ownership, while the government has only regulatory authority. In this economic system, the production of goods is in accordance with the demand from the consumers. The competition is very high, thus for a business to succeed and persist needs to make products with the highest possible quality for the lowest possible price.
One other characteristic of the market economy is that every business has total freedom when it comes to choosing what to produce and what amount to produce it. The businesses don't produce equally for all areas where they deliver their products, but instead, there are big differences in the distribution. This is based on how much of their products are in demand in a particular area, where there is higher demand there is bigger delivery and vice versa.
