None of the provided responses accurately define specialization in a free market economy.
Specialization refers to the process by which individuals, businesses, or countries focus on producing a limited range of goods or services in order to increase efficiency and productivity. It allows for a more productive allocation of resources, as producers become more skilled and efficient in their specific areas of focus.
In a free market economy, specialization often leads to greater overall output and the creation of goods and services that meet consumer demand more effectively.
