Oa Asia
Christopher Columbus mistakenly believed he had discovered Oa Asia.
To determine what Christopher Columbus mistakenly believed he had discovered upon reaching land, we need to consider historical facts. Christopher Columbus embarked on his expeditions during the late 15th century, seeking a western route to Asia while under the impression that the Earth was smaller than it is.
To find out which land Columbus mistakenly believed he had discovered, we can eliminate options based on his intended destination. Let's review the options:
Oa Asia: This option aligns with Columbus' original intention, so it is unlikely that this is the correct answer.
Ob Africa: Columbus initially believed he had reached Asia, so Africa does not match his intended discovery.
c. Australia: Although Columbus had sailed to the New World, he did not encounter Australia. This option can be ruled out.
Od Antarctica: Columbus did not reach Antarctica during his voyages. Hence, this does not align with his mistaken belief.
Therefore, the correct answer is Oa Asia. Christopher Columbus mistakenly believed he had discovered a western route to Asia when he actually arrived in the Americas.
