The answer is c when the substances are evenly spread out.
I believe the answer is c
Potassium has the greatest influence on the resting membrane potential. Resting membrane potential is caused by the differences in the concentrations of ions inside and outside the cell. At resting membrane potential there are more sodium ions outside the neuron and more potassium ions inside the neuron. For a neuron the resting membrane potential is about -70 mV.
