If the Soma of a Neuron Became More Permeable to Potassium

If the soma of a neuron became more permeable to potassium, which statement below best describes the graded potential that would be generated in the soma?

A) Potassium would reach its equilibrium potential and the voltage inside the cell would not change.
B) Potassium would leave the cell, causing the membrane to hyperpolarize.
C) Potassium would enter the cell, causing the membrane to depolarize and reach threshold.
D) Potassium is a cation; therefore, it would cause an excitatory depolarization.
E) Potassium is an inhibitory second messenger; therefore, it would cause amplification of the graded potential.
