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. 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. Action potential generated at site A arrives at site B
C. Permeability to `Na^(+)` decreases and is quickly followed by a rise in permeability to `K^(+)` at site A. Polarity at the site B is reversed and hence called repolarised.
D. `Na^(+)` channels get closed and `K^(+)` channels get opened at site -A. Depolarization and opening of `K^(+)` channel at site -B

Answer

C
