how did the adoption of a money system contribute to the modern economy?
increased the value of silver as it was used for coins
led to the development of a class of banking professionals
resulted in decreased trade because of limited coins available for use
put money in the hands of merchants at no cost to allow for unbridled economic growth

Explanation:

The adoption of a money system led to the development of banking professionals. Before money systems, trade was often barter - based. With the introduction of a standardized money (like coins), there was a need for entities to store, exchange, and manage this money. This led to the rise of banking - related activities and thus a class of banking professionals.
Increasing the value of silver (if it was used for coins) is a narrow and not the main contribution. A money system generally increased trade (not decreased as in option C). And putting money in merchants' hands at no cost is an incorrect economic concept as money has its own production and distribution costs.

Answer:

Led to the development of a class of banking professionals
