One can use D2O for what's known as a "deuterium exchange" experiment.  Certain protons (1H) will exchange with deuterium (2H), such as those you have mentioned.

I'm not going to give you the whole answer because it's fun coming up with the answer yourself :), but consider whether or not deuterium is NMR-active, and the consequence of the 1H-NMR spectrum.
