Your friend is poking your skin with two pins a few millimeters apart at the same time.Visually,you can see there are two pins,but you can only feel a single pen poke.This is probably because:

A)both pens are activating the same receptor.
B)both afferent neurons converge on the same interneuron.
C)the receptors in both skin areas utilize the same afferent neuron.
D)both sensations are grouped together in the somatosensory cortex.
