Q1. Which is the largest ocean in the world?
A Arctic Ocean
B Pacific Ocean Correct
C Indian Ocean
D Atlantic Ocean
Explanation
The Pacific Ocean is the largest ocean on Earth by area and volume, covering a greater surface than any other ocean basin. The Atlantic Ocean is the second-largest, but it is smaller than the Pacific. The Indian Ocean is also extensive, yet it ranks below both the Pacific and Atlantic in size. The Arctic Ocean is the smallest and shallowest of the major oceans. Therefore, the ocean named as the Pacific matches the standard geographical classification and the official key.
