At -150, the molecules of oxygen…
…would sound more correct than “the atoms of oxygen”.
Option C looks better, but I have a different interpretation of “reached”. I could say that the temperature JUST reached -219, in which solid state is obviously not present (since no freezing has taken place yet), so option C can also be risky.
But then, if given a choice, option C would be better than option A. I think the question intended for “reached” to mean “already reached” rather than “just reached”.
