Answer:
The correct answer is he discovered the sea route around Africa
Step-by-step explanation:
Bartolomeu dias was a Portuguese sailor from the Age of Exploration. As Portugal started to explore the open seas for new markets and products, the Monarch funded several expeditions.
In 1487-88, Bartolomeu dias was exploring the coast of Africa as he went further South. Eventually he discovered the first Sea route from Europe to Asia, via the tip of modern-day South Africa.
Before the discovery of this sea route, all trade and transport between Europe and Asia took place over land.
