Correct Answer
A. ({(-1,y):2\le y\le5})
Concept
The first component is always (-1), and the second varies in ([2,5]). This gives a vertical line segment.
Why this answer is correct
The correct answer is A. ({(-1,y):2\le y\le5}). The first component is always (-1), and the second varies in ([2,5]). This gives a vertical line segment.
