The measure of chord JK will be 9 units. Hence, option A is correct.
What is a sector ?
A sector is formed by two radii and the intercepted arc on the circle.
Here, The angle subtended by the sector at the center is called Central Angle.
It is given that the sector , GH and JK are congruent.
Since they are congruent the angle subtended by them at the center will be equal.
The measure of ∠GOH = 47 degree
∠KOJ = ∠GOH = 47 degree
So, the length of chord
GH = JK = 9 units
Therefore , The measure of chord JK will be 9 units.
Hence, option A is correct.
