The term that refers to an exact location in space is a point. A point has no dimensions—meaning it has no length, width, or height—making it a fundamental concept in geometry. It simply indicates a specific position within a coordinate system or in various geometric contexts.

In contrast, a line is defined as a straight one-dimensional figure that extends infinitely in both directions but does not have boundaries or a defined starting point. A plane, on the other hand, is a two-dimensional flat surface that continues infinitely in all directions. An angle is formed by two rays that share a common endpoint and measures the rotation between them. Thus, while the other options involve more complex geometric constructs, a point stands alone as the most basic unit of geometry, representing a precise location without any extent.
