Principles of Action Potential
Action potential is a brief, rapid and large depolarization of the membrane potential of a cell. It is an important phenomenon in the transmission of information in the nervous system. The following are the principles of action potential:
All or None Law
This principle states that the amplitude and duration of an action potential are constant and independent of the strength of the depolarizing stimulus. In other words, either an action potential is generated or it is not, and the strength of the stimulus does not affect the magnitude of the action potential. When the stimulus is strong enough to reach the threshold value, an action potential is generated. If the stimulus is too weak, no action potential is generated. This principle is important in the coding of information in the nervous system.
Threshold Value
The threshold value is the minimum depolarization required to generate an action potential. If the depolarization is not sufficient to reach the threshold value, no action potential is generated. The threshold value is different for different types of cells and can be influenced by various factors such as temperature and drugs.
Propagation of Action Potential
Action potential can be propagated along the axon of a neuron. It travels in one direction, from the axon hillock to the axon terminal. The speed of propagation can be influenced by factors such as axon diameter and myelination.
Conclusion
In summary, the principle of all or none law states that the strength of the depolarizing stimulus does not affect the magnitude of the action potential. The threshold value is the minimum depolarization required to generate an action potential, and action potential can be propagated along the axon of a neuron. These principles are important in the transmission of information in the nervous system.

All or none principle states : the nerve impulse is either conducted totally or not conducted at all.
an action potential occurs in the membrane of axon of a neuron when depolarization reaches a certain level called threshold potential.
the action potential occurs in response to a threshold stimulus or supra threshold stimulus but does not occur at subthreshold stimuli.
So, option-d concurs .
opt-a is incorrect because not all stimulus produce's action potential.
opt-b not all cells are excitable to generate action potential.
opt-c potential difference ranges between. -80mv to -40mv.
