Text Solution

Verified by Experts
The correct answer is:
C

The resting membrane potential is maintained by the sodium-potassium pump, which actively transports out and in, contributing to the positive charge outside and negative charge inside. If this pump stops, would accumulate inside and would leak out (since the membrane is more permeable to ), gradually equalizing ion distribution. This leads to the loss of polarity across the membrane. It wouldn't become more negative or hyperpolarized-it would become depolarized.
