Answer:
The correct answer would be option C, An economy's production of two goods is efficient if, it is impossible to produce more of one good without producing less of the other.
Explanation:
An economy's production is said to be efficient for two goods if it is impossible to produce more of one good without producing the less of the other good. When there is no effect if one product is produced more, and the other product does not have to be reduced in order to accommodate the increase in the production of one good, then the production of two goods are said to be efficient. It means, that the economy has all resources to accommodate the number of goods produced. For example, if automobile industry wants to increase the number of cars it produce in an year, then if the economy is efficient, then there will be no decrease in the production of other goods like, motorbikes, carts, etc.
