Cost Performance Index (CPI) is a measure of the cost efficiency of budgeted resources expressed as the ratio of earned value to actual cost. A CPI of 1.0 means the project is exactly on budget, that the work actually done so far is exactly the same as the cost so far. Other values show the percentage of how much costs are over or under the budgeted amount for work accomplished. CPI = EV/AC. CPI Greater than 1.0 = Under planned Cost. CPI Exactly 1.0 = On planned cost. CPI Less than 1.0 = Over planned cost. Therefore right answer is C. [PMBOK 6th edition, Page 267] [Project Cost Management]
