Answer:
The correct answer would be C, Producers and Consumers.
Step-by-step explanation:
An Economy is something where activities of production, consumption, distribution, and every kind of trade is taking place. Huge money supply takes place in an economy. It is sometimes called the trading hub or trading center, where all trades are occurring. So the option C is the appropriate one because it is true that economy exists just because of the interaction between the producers and the consumers. If there is no producer who produces a product, there won't be a consumer who consumes it, there won't be any money involved, there won't be any trade taking place. So Economy exists just because of the interaction between the producers and the consumers.
