Concentration of $$\text{K}^+$$ ions inside a biological cell was found to be 25 times higher than that outside. The magnitude of the potential difference between the two sides of the cell is close to (2.303 RT/F can be taken as 59 mV; difference in concentrations of other ions can be taken as negligible.)

A

4.2 mV

B

195 mV

C

82 mV

D
