Which development most influenced the expansion of trade?
1.creation of guilds
2.growth of urban centers
3.increased food production
4.efficient farming techniques

The development that influenced expansion of trade the most is the growth of urban centers.

Explanation:

First of all, the creation of guilds wouldn't be correct because even though the guild could have focused on a single industry, they needed to find customers, because there is no trade without customers. Actually, production would be the only thing that could have improved by the creation of guilds.

In second place 3 and 4 the answer would have also improved production instead of expansion of trade.

The correct answer is 2 because, with the growth of urban centers, the general population rose and also the needs of the urban centers. Thus, the increase in consumption would have increased as well as the need to purchase services and goods to satisfy their needs. As a consequence with demand and an increasing number of customers, the trade would have also increased.
