A line segment here is represented by each alphabetical point with a line above it to show its a line segment
A line segment is also a straight line
Let's say we have a line, the beginning of the line is A and the end is B, so the line segment is segment AB
In this case, we see that there are 4 lines
WX, XZ, YZ, WY
(you read the lines from left to right and from up to down)
Answer: C) WX, XZ, YZ, WY
I hope this helps!
