Answer:
Options B and C
Step-by-step explanation:
Here, we want to select the set of points in which the difference between their vertical distance is less than 6 units
Let us consider the options one after the other;
A. 1-4-(-5) = 6.4
B. 0.2-(-1.6) = 0.2 + 1.6 = 1.8
C. 2.5-(-3) = 5.5
D. 7-(-1) = 7 + 1 = 8
So we can see that the options B and C are separated by vertical distance less than 6
