reply toThe most accurate statement from the options provided is: "Estimate at completion and estimate to complete are the same thing." This statement aligns with standard project management terminology. The Estimate at Completion represents the expected total cost of completing a project, incorporating both actual costs incurred to date and an estimate for remaining work. Similarly, the Estimate to Complete refers to the projected cost to complete the remaining work in a project. According to the Project Management Institute (PMI), the EAC is calculated by adding the actual costs incurred to date to the Estimate to Complete (ETC), which is the remaining budget needed to complete the project. Therefore, the EAC includes both the costs incurred and the estimated costs to finish the project. This aligns with the notion that EAC and ETC are indeed synonymous in project management terminology
