Answer: B

Explanation:

The Schedule Performance Index (SPI) is calculated using the formula:

SPI=Earned Value (EV)Planned Value (PV)text{SPI} = frac{text{Earned Value (EV)}}{text{Planned Value (PV)}}SPI=Planned Value (PV)Earned Value (EV)

Given:

Total Budgeted Hours = 12,000 hours

Planned Completion = 75%

Percent Complete = 66%

EV=12,000×0.66=7,920 hourstext{EV} = 12,000 times 0.66 = 7,920 text{ hours}EV=12,000×0.66=7,920 hours PV=12,000×0.75=9,000 hourstext{PV} = 12,000 times 0.75 = 9,000 text{ hours}PV=12,000×0.75=9,000 hours SPI=7,9209,000≈0.88text{SPI} = frac{7,920}{9,000} approx 0.88SPI=9,0007,920≈0.88

So, the correct answer is B. 0.88.
