Assertion (A): In depolarization process, there is a psotive charge on the outer side of a nerve fibre and a negative charge on its inner side
Reason (R): During depolarization, permeability of plasma membrane increases for sodium ions so Na+ move to outer side of the membrane and K+ enter into the nerve fibre through it
1. Both A & R are true and the R is the correct explanation of the A.
2. Both A & R are true but the R is not the correct explanation of the A.
3. A is true statement but R is false.
4. Both A and R are false statements.
