Could a human breathe in liquid oxygen without dying?

Nope. We are not adapted to that degree of cold or that concentration of oxygen.

NO!!! It is too cold, It would freeze the lungs and blood. Remember what happens to bananas or eggs in liquid nitrogen, they become brittle and break . Liquid oxygen is even colder.

No. Oxygen can not exist as a liquid above -118C. Breathing it would not be good.

Even if it were possible to do so, it would instantly freeze his internal organs, killing him.

Liquid oxygen, like all very low temperature liquids, would cause severe burns; it would also instantly freeze the lung membranes and the water-based mucoid films covering lung tissues.
In any case we cannot absorb oxygen directly: it must be dissolved into the water-based mucoid liquid which covers the surfaces of our alveoli. That cannot happen when that liquid is absent or when it is frozen.
There is a liquid we can breathe though: oxygenated fluorocarbons. It’s hard work to breathe it as it doesn’t flow as easily as air, but it has been successfully trialled on animals. There’s a (now deleted) scene in the movie “The Abyss” which genuinely shows a rat breathing the stuff. You’ll only now see that scene on the original home video release, as all DVD/BluRay/streaming and subsequent cinema re-releases no longer have that scene.
No human trials of liquid breathing have ever officially been approved but it has been suggested as a method of saving severely premature babies with underdeveloped lungs.

No. That stuff would be at minus 184 degrees celsius or colder..

Lake Baikal is 100% oxygen. And it's said that humanoids live under it.
