From the options provided, a chord is a line segment with both endpoints on the circle.
- OCE: This does not connect two points on the circle as 'O' is typically the center of the circle, assuming the letter 'C' and 'E' are points on the circle.
- OCH: Similar to the previous, 'O' is the center of the circle.
- O FG: Again, 'O' is not a point on the circumference.
- FC: This connects two points on the circle.
Therefore, the chord other than the diameter of the circle is FC.
