Answer:

A chord that passes through the center of the sphere.

Step-by-step explanation:

In plane geometry, a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle. A chord that passes directly through the center of the sphere and to the other end is determined to be the diameter.
