Answer:
<h2>A. FE</h2>
Step-by-step explanation:
In geometry, a chord is defined as any line that joins two points of the circumference.
So, in the given graph we have that AC, AB, EB are chords, because they joint two points of the circumference.
On the other hand, FE, FD, FC, FA, FB are not chords, because they only joint a point on the circumference with the center, so they represent the radius.
Therefore, among the options A. FE doesn't represent a chord.
