Which Sensory Processing Pattern, as Outlined in Dunn's Model, Is

Which sensory processing pattern, as outlined in Dunn's model, is correctly described below?

A) Registration/Bystander: Low neurological threshold, passive self-regulation (respond less to available sensation, missing aspects of sensory input, require a lot of input to "get going")
B) Sensitivity/Sensor: High neurological threshold, passive self-regulation (driven to obtain sensation in greater intensity, frequency, or duration than that routinely available)
C) Seeking/Seeker: High neurological threshold, active self-regulation
D) Avoiding/Avoider: Low neurological threshold, passive self-regulation
