Answer:
He located a water route to Asia.
Step-by-step explanation:
Christopher Columbus was a navigator. He made four trips across Atlantic Ocean from Spain in 1492, 1493, 1498 and 1502. He wanted to discover a sea route from Europe to Asia but he failed to do so, but he found the American continent. People consider his as the discoverer of America.
His exploration led to Columbian Exchange and later when the Americas was colonized by other European powers it led to the death of millions of native Americans.
The water route to Asia from Europe was discovered by Vasdo Da Gama in 1498.
So, all the options are correct except He located a water route to Asia.
