Answer:
vanishing point
Explanation:
One-point perspective does convey depth, but it has limited applications due to its reliance on a single ___
--> all different types of perspective (one, two, three, four ,five, etc) all rely on vanishing points, so it would be easy to conclude that the answer is vanishing point. There isn't really much else that could go in that blank anways- so it's overall pretty straightforward :)
