The answer is choice D) Two rays that share the same endpoint
======================================
Here's a full breakdown of the four choices
A. False. If the ray and line aren't touching, then an angle can't be formed.
B. False. Parallel lines never cross. The same issue as before (in part A) comes up.
C. False. Again the rays need to meet up somehow.
D. True. If you have two rays that share the same endpoint, then they form an angle. Think of it like a pair of scissors. Each blade is a ray. The blades are joined at a common node to allow the blades to swing open or closed. You could have an angle formed by line segments or lines, but they would have to intersect in some way.
