Given below is the diagrammatic representation of impulse conduction through an axon.

Select the option with the incorrect information about impulse conduction at points A and B.

Options

A. Option1 An electric current flows on the inner surface from site A to B and on outer surface, from site B to A to complete the circuit.
B. Option2 Action potential generated at site A arrives at site B
C. Option3 Permeability to `Na^(+)` decreases and quickly followed by a rise in permeability to `K^(+)` at site A. Polarity at the site B is reversed and hence called repolarised.
D. Option4 `Na^(+)` channels get closed and `N^(+)` channels get opened at site -A Depolarisation and opening of `N^(+)` channel at site -B

Answer

C
