To find the length of AB, we can use the distance formula:
AB = sqrt((x2-x1)^2 + (y2-y1)^2)
Given A(-4, 3) and B(1, -3):
AB = sqrt((1 - (-4))^2 + (-3 - 3)^2)
AB = sqrt(5^2 + (-6)^2)
AB = sqrt(25 + 36)
AB = sqrt(61)
AB ≈ 7.8 units
Therefore, the measurement that is closest to the length of AB in units is D) 7.8 units.
