calculate the interval time where the project is over the planned budget, giving the following definition

The data given in the table below shows PV, EV, and AC values in thousands of dollars for the first 7 weeks of a project's execution before its completion ) Activity ID A B Week Number 1 2 3 4 5 D E F PV (S) 7000 10000 15000 23000 30000 50000 70000 EV (S) 10000 17000 20000 25000 30000 45000 60000 AC (S) 8000 15000 20000 30000 40000 55000 75000 6 7 G Indicate the interval of time where the project is over the planned budget? Select one: O a. From week 1 to week 3 O b. On week 3 O c. From week 1 to week 7 O d. From week 3 to week 7 The Earned Value (EV): Terminology Below are the basic elements for calculating EV and use its figures to make future project performance projection: EV - Earned Value: This is the real budgeted cost, or "value", of the work that has actually been performed to date. AC - Actual cost of work performed: The cumulative total costs incurred in accomplishing the various project work packages. PV - Planned Value: A cost estimate of the budgeted resources scheduled across the project's life cycle (cumulative baseline)
