Which of the following BEST describes the general idea of the project?

Project objectives define what the project aims to achieve, providing the overarching goals and reasons for undertaking the project. They describe the desired outcomes and the general idea behind the project's existence.

Project milestones are significant points or events in the project schedule, marking progress, but they do not describe the overall idea or purpose of the project.

Project assumptions are factors believed to be true for planning purposes, but they do not define the project's general idea or what it sets out to accomplish.

Project scope defines the specific work required to deliver the product, service, or result, but it describes what will be done, not the more general why or overall idea/goal.
