A) is -60 to -70 mV more negative inside than outside.
B) is -60 to -70 mV more positive inside than outside.
C) has a potential of -60 to -70 mV on both sides of the membrane.
D) must build up a potential of -60 to -70 mV inside the cell before it can carry an action potential.
E) must build up a potential of -60 to -70 mV outside the cell before it can carry an action potential.

Resting potential refers to the electrical potential difference across the neuron's membrane when it is not actively transmitting a signal. The negative sign indicates that the inside of the cell is more negative than the outside. Therefore, choice A is correct as the cell is -60 to -70 mV more negative inside than outside.
