Hint: In 1796, a young Scottish physician became the first person to discover River Niger. While during an exploration from Bechuanaland between 1851 and 1853, river Zambezi was discovered. The period between 1492 and 1504 with four round-trip voyages between Spain and the Americas, finally the continent of America was discovered. The first person circumnavigated the world from 1519 to 1522.

Complete answer:
The above question includes four discoverers and their discoveries. However, only one pair is incorrect. Let's look at the pairs given above and examine their discoveries to see if they are correct or not.
(A) River Niger is an important and one of the longest river. It is a major river and also a source of water in the Sahara desert. A young Scottish Physician, Mungo Park in 1796 discovered the river Niger. Mungo discovered the upper part of the river. While exploring the other and the lower part he got killed by a local resident. Thus the lower part remained unknown for a long time.
(B) Livingstone, born in Scotland was a Scotting doctor, missionary, and an explorer who lived in the 1800s. He is famously known for his discovery of the Zambezi river, made through exploration from Bechuanaland between 1851 and 1853.
(C) It is believed that through the four voyages of Christopher Columbus between 1492 to 1502, he discovered the continent of America. He was an Italian explorer and navigator, born in Genoa, Italy.
(D) Bartholomew Dias was the first European to round the southern tip of Africa. He opened the way for sea routes from Europe to Asia. However, it was Ferdinand Magellan, five thousand years ago who circumnavigated the earth.
Thus with the above explanation and analysis the incorrect pair is-D.

Therefore, option D is the right answer.

Note: David Livingstone, after discovering river Zambezi also discovered great Victoria falls in 1855. Christopher Columbus also determined to discover or find a direct sea route from Europe to Asia, but he never did.
