The correct option is C Metals are malleable
Metals overcame the drawbacks of money in the form of grains and cattle. The other forms of money were perishable and hence, were replaced by the durable metals. The sturdy and strong feature of metals also enabled the coins to retain their shape for longer periods of time. Additionally, the malleable nature of metals made it convenient to make coins of various shapes. All these features made metals ideal for making coins. Some of the widely used metals were copper, silver, and gold.
