Hi ashpine17!
To your first question, I don't see material from the stimulus that would make (A) true in a non-ice age. To the contrary, the stimulus indicates the proportions in the vapor and seawater are different.
To your second, yes, from the material in the stimulus, we don't know the specific proportion of oxygen-16 and oxygen-18 in seawater, though we know that there is a greater proportion of oxygen-18 in the seawater in comparison with vapor.
