Answer:
Option (3).
Explanation:
The action potential may be defined as the change in the electric potential of the cell that helps in the propagation of the nerve impulse. The resting membrane potential of the cell is -70mV.
Threshold potential may be defined as the minimum potential required to transmit the nerve impulse. If the difference between the excitatory signal and inhibitory signal exceeds the minimum intensity, known as threshold. The propagation of nerve impulse occurs.
Thus, the correct answer is option (3).
