The main idea here is that scope refers to the extent or range of something. In everyday use, you might talk about the scope of a project—how broad it is, what topics or areas it covers—which aligns directly with the definition “the extent or range of something.” The other options describe a border or edge, a type of telescope, or a legal cap, none of which convey the idea of overall breadth or coverage. So the choice that states the extent or range fits best.
