Answer: B voltage-gated potassium channels
Explanation:#
Tetraethylammonium is a pH- potassium channel blocker.
Therefore, it prevents the escape of potassium ions from the axoplasm, which makes it ( axoplam) positive from the rise in potassium ions concentration , since potassium ion is positive charged and intracellular ion . This initiate repolarization which returns to membrane state potential.
Since it is pH -potassium ion blocker; it does not affect the voltage-gated sodium ion channels, so action potential can occur. But after the sodium gated channels were closed,action potential drops but the concentration of potassium rises because :
1. They are naturally intracellular ions
2. They cannot leave the axoplasm because the channels has been shut. Therefore this stabilizes the membrane potential
