The answer is C. Better cannons and ship rigging
During the 16th-17th century, is the height of sea trading. Voyages were longer and farther. Most voyages focused on trading rather than warfare. However, it is inevitable to engage in such warfare when necessary. Artillery such as cannons were redesigned to be lighter and more compact so they would consume less space. Before, cannons occupy much space in the ship thus, the goods that merchants can load on the ship are reduced. Ship rigging was also improved by adding up to 6 masts overall. This was done so that large ships can sail at great distances and reduce the number of trips to cut cost.
