Correct Answer is A. The key to the answer is what happens to SV and SPI when your project is finished. Assuming "finished" means you completed all your planned work (PV) and deliverables. If so, then your Earned value (EV) would be equal to your Planned value (PV), and SV would be zero and SPI would be 1.0. In this question since SPI is not 1.0 then you have not "finished" the project. This eliminates answers C and D, and since there is no way to determine if additional scope was added, answer B is eliminated. That leaves answer A as the only choice.
