A half-infinite line (also known as a half-line) with one of the two points and is commonly used to represent a ray. The endpoint of a ray is point S. The correct option is B.
<h3>What is a ray?</h3>A half-infinite line (also known as a half-line) with one of the two points and is commonly used to represent a ray. It is assumed to be infinite.
Given that Two lines extend from point S to create a right angle. The vertical line extends from point S through point R. The horizontal line extends right from point S through point T.
Also, A third line extends right and up from point S through point U. This can be drawn as shown below.
Now, since all the ray starts from point S, therefore, the endpoint of a ray is point S.
