Q: What are the performance measurements for the Schedule Control process?

a) SV (PV - EV)  and SPI (PV / EV)
b) SV (EV - AC) and SPI (EV / AC)
c) SV (EV - PV) and SPI (EV / PV)
d) SV (EV - BAC) and SPI (EV / BAC)

A: c)

Schedule Variance (SV) = EV (Earned Value) - PV (Planned Value)
Schedule Performance Index (SPI) = EV / PV

Further definitions:
Earned Value = Estimated value of work actually accomplished on the project
Planned Value = Estimated value of worked planned to be done on the project
