Concept:Tradable goods should be divisible, meaning they can be split into smaller units without losing their value.
Explanation:Divisibility is a key quality of tradable goods.
It allows a good to be divided into smaller parts, and each part still holds its original value.
For example, a bar of gold can be cut into smaller pieces, and each piece remains valuable gold.
This makes trading flexible because buyers and sellers can exchange smaller or larger quantities according to the value of the transaction.
Goods that are perishable, heterogeneous, or not easily standardized are harder to trade.
Among the given options, divisibility is the quality that best supports smooth trading.
Hence, the correct answer is divisibility.
Answer:C. divisibility
