skip 0/10 complete

Explanation:

Step1: Recall radius definition

The radius of a circle is the distance from the center of the circle to any point on the circle.

Step2: Identify center and points

Point C is the center of the circle. Points A, B, and D are on the circle. So, CB, AC, and CD are radii.

Step3: Analyze BA

BA is a diameter (a line segment that passes through the center and has its endpoints on the circle), not a radius.

Answer:

BA
