Answer:

C. BE:KA

Step-by-step explanation:

The segments that have a ratio of lengths 1:2 are BE and KA.

A diameter is a straight line that touches 2 points on the circumference of a circle and touches the point at the center. KA is the diameter.

A radius is a straight line touches a point on the circumference of a circle and touches the point at the center. BE is the radius.

The radius of a circle is half the diameter.

[tex]r=\frac{d}{2}[/tex]

If the radius is 1 cm, then the diameter is 2 cm.
