The implication of the test question is that it won't work properly. If you assume that the triangle under the 10V source and the black clip of the oscilloscope are common grounds, then the capacitor will be shorted and you'll have the full 10V, in phase, across R1. And that's what you see on the scope, more or less, again assuming that you have a high-impedance input on the scope and perhaps a 10X probe. But IMO, none of those assumptions is really justified without explicitly stating them.
For a high-impedance scope/probe and no common ground, you see an amplitude less than 10V and out of phase (leading) the source voltage, varying with frequency. But you can't answer that question precisely without knowing the frequency of the AC source, so that's your clue that any such answer is not what the question is looking for.
