Answer:
The chord is bisected ⇒ 3rd answer
Explanation:
* Lets revise some facts in the circle to solve the problem
- A chord in a circle is the segments whose endpoints lie on the
circumference of the circle
- A diameter of a circle is a chord passes through the center of the
circle
- The diameter is the longest chord in the circle
- Any line passes through the center of the circle and perpendicular
to a chord on the circle bisects it
* Lets solve the problem
∵ The diameter of the circle passes through the center of the circle
∵ The diameter intersects a chord of a circle at a perpendicular
∴ The diameter is perpendicular to the chord
∵ Any line passes through the center of the circle and perpendicular
to a chord on the circle bisects it
∴ The diameter bisects the chord
* The chord is bisected
