The diameter of a circle is the length of the line segment from one end of the circle to the other end of the circle, which in this case is segment EF, given by option C.
-----------------------
When we are studying a circle, we need to understand two very important concepts, the radius and the diameter.
- Radius: The radius of a circle is the length of the line segment from the center of the circle to it's circumference.
- Diameter: The diameter of a circle is the length of the line segment from one end of the circle to the other end of the circle.
- In length, the diameter is always twice the radius.
-----------------------
In this question:
- The center is O, so both OE and OF are radius.
- The ends are E and F, so the diameter is EF, and the correct option is C.
