The correct answer is B) goods were traded for goods.
Goods were purchased from the East without an abundance of gold and silver in that goods were traded for goods.
It was a kind of barter, where goods were traded for other equivalent goods regarding the value of the goods. So merchants exhibited their products and people interested that product approached him with their own goods and established the value of their products and then the equivalent for the exchange. So for instance, "x" amount of rice or wheat were the equivalent of "x" amount of salt.
