Good question.
We can reach C as a correct answer even by POE. The other options are wrong or not mentioned in the passage at all.
However, in this case, I believe the fact that the Arctic ocean is frigid in not an assumption we make or information from the outside we bring into the passage but is a fact that is universally recognized.
I hope this helps
Yeah I checked other options as well which are nowhere and marked C, but got a doubt about this kind of questions to assume or not
