$A$ state where the axonal membrane has a positive charge on the outside and a negative charge on the inside.

Vedclass · Answer

(A) nerve fiber is said to be polarised when it is in a resting state.In this state,the axonal membrane is more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.Consequently,the outer surface of the axonal membrane becomes positively charged due to the higher concentration of $Na^+$ ions outside.Simultaneously,the inner surface becomes negatively charged due to the presence of negatively charged proteins and $K^+$ ions inside.This difference in electrical charge across the membrane is known as the resting membrane potential,and the fiber is described as polarised.
