Of the four oceans, which is the smallest?

Answer 1

Indian Ocean, Pacific is the biggest, then Atlantic, then Antarctic, then Indian.

Answer 2

There are actually five oceans (Atlantic, Pacific, Indian, Southern, and Arctic). In descending order of size they go like this:
Pacific (largest)
Atlantic
Indian
Southern
Arctic (smallest)

The people that said "Indian" is the smallest are not 100% wrong, though I would consider it an incorrect answer. The only way it is correct is if you don't consider the Southern and Arctic oceans to really be oceans. There is a valid argument against the Southern ocean, but the Arctic has its own oceanic basin separate from the Atlantic, and in my opinion that makes it a bona fide ocean. Here's a quote from wikipedia:

"The major oceanic divisions are defined in part by the continents, various archipelagos, and a number of other criteria; these divisions are (in descending order of size) the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean (which is sometimes reckoned instead as just the southern portions of the Pacific, Atlantic, and Indian Oceans), and the Arctic Ocean (which is sometimes considered a sea of the Atlantic)."
