Answer

B.Ions

Explanation

Axon is a long slender projection of a nerve cell or neuron that conducts electric impulses away from the neuron’s cell body. The neuron maintains a resting membrane potential. Due to high concentration of potassium inside the neuron, there is a concentration gradient attempting to force potassium out of the cell. Similar forces will attempt to move sodium ions into the neuron

the answer is d (apex) good luck : ))

i think its the first one
