Since segment XY passes through a sphere with Center P. Points X and Y lie on the sphere, a term which best describes XY is: B. chord.
In Mathematics and Geometry, the chord of a circle is a line segment that joins any two (2) points on a circle. This ultimately implies that, a chord simply refers to the section of the line that is used for connecting two separate points on a circle.
Furthermore, a chord refers to a line segment that consist of a pair of end points that lies on the circumference of a circle or a sphere.
In this context, we can reasonably infer and logically deduce that a chord is a terminology which best describes segment XY because it passes through a sphere with Center P, and points X and Y lie on the sphere.
