How Does the Size and Shape of the Endplate Potential

How does the size and shape of the endplate potential change when recorded at different distances from the endplate at the NMJ?

A) The EPP does not change when recorded at different distances from the NMJ.
B) The EPP has the same amplitude but has a slower time course when recorded at increasing distances from the NMJ.
C) The EPP has reduced amplitude but the same time course when recorded at increasing distances from the NMJ.
D) The EPP has both a reduced amplitude and slower time course when recorded at increasing distances from the NMJ.
E) The EPP has both an increased amplitude and slower time course when recorded at increasing distances from the NMJ.
