Final answer:
The most basic elements in space, serving as the building blocks for everything else, are points. A point is an exact location in space and is fundamental in both geometry and coordinate systems.
Step-by-step explanation:
The coordinates in space, without dimension or area that are the most basic elements and building block for everything else, are c. Point. A point is an exact location in space and serves as the cornerstone for more complex geometric structures such as lines and planes. In geometry and mathematics, a line might be considered a series of points extending infinitely in both directions, and it often helps create forms and shapes. When dealing with coordinates, we use sets of numbers to specify the location of a point in a space or on a plane. For example, in a three-dimensional coordinate system, we use three coordinates (x, y, z) to define a point's position, with the Cartesian coordinate system utilizing unit vectors î, ĵ, and Ê to establish a standard right-handed orientation for its axes.
