Quantization of charge in experimental data

A team of particle physicists are trying to calibrate their detection apparatus. To test their equipment, they graph the number of particles detected as a function of the charge of the particle, where

e

is the magnitude of an electron's charge.

Based on the graph, should the physicists be concerned about the equipment, and for what reason?

(Choice A)
Yes, the physicists should be concerned, since particles can’t have the charges shown
(Choice B)
No, the physicists should not be concerned, since the charges are quantized
(Choice C)
No, the physicists should not be concerned, since the width of the data bins is sufficiently small
(Choice D)
Yes, the physicists should be concerned, since the width of the data bins is too large
