The correct answer is A) becoming more self-sufficient.

Trading centers in other countries helped the mother country in many ways except for becoming more self-sufficient.

Trading centers gather sufficient raw materials to the mother country as well as providing manufactured goods. Trading centers allowed the mother country to have the natural resources needed to process them and manufacture other things or to sell the natural resources to its citizens. That was the case of minerals, gold, silver, ivory, vegetables, among others.
