Answer:
A. European rulers were better able to compete for wealth and power around the world.
Explanation:
Improvements in navigation and shipbuilding allowed European sailors to travel faster, and "discover" many new geographical areas, where European nations would establish colonies to extract wealth and engage in trade.
The first European country to do so was Portugal, followed by Spain. These two countries colonized vast areas of the world, from the coasts of Africa to the Americas, and Asia.
A century later, France, Great Britain and the Netherlands would join the colonial adventure, competing amongst them for wealth and power around the world.
