b) Potassium (K+) concentration is higher outside the cell, and sodium (Na+) concentration is higher inside the cell.
c) Potassium (K+) and sodium (Na+) gradients are maintained by active transport in a resting mammalian neuron.

Answer:C

Explanation:

Resting Membrane Potential (RMP) is the charge difference represented as voltage difference across a nueronal cell membrane at rest.

It has a value of -50 and -75mV.

Graphically it represents the flat plateau at the last part of the curve of action potential (check the attachments)

In a normal resting cell after Action potential ;for example nuerone,the intercellular layer has more potassium ions, while the extracellular layer has more Sodium ions .

These ions have special channels called sodium and potassium channels for movement in and out of these ions by active transports.

The movements of these ions across the membranes generated electrical potential difference for action potential.
