In a circle, a chord is a line segment with both endpoints on the circle.
Based on the given options:
- CE represents a segment from point C (the center) to point E (on the circumference), which is not a chord.
- CH is not mentioned as a point on the circumference; thus it cannot be identified as a chord.
- FG connects points F and G on the circumference, making it a valid chord.
- FC connects point F (on the circumference) to point C (the center), which is not a chord.
Therefore, the correct answer is:
FG (upper F upper G) is a chord other than the diameter of the circle.
