According to the question, the schedule variance (SV) of the project is zero. A value of 0 indicates that the project is right on target. Schedule variance (SV) is a measure of schedule performance on a project. The variance notifies that the schedule is ahead or behind what was planned for this period in time. The schedule variance is calculated based on the following formula: SV = Earned Value (EV) - Planned Value (PV) If the resulting schedule is negative, it indicates that the project is behind schedule. A value greater than 0 shows that the project is ahead of the planned schedule. A value of 0 indicates that the project is right on target.

Answer option C is incorrect. The negative SV means that project is behind the schedule.

Answer option D is incorrect. This result can be drawn by looking at the cost variance (CV) of the project.

Answer option B is incorrect. The positive SV depicts that the project is ahead of the planned schedule.
