Respuesta :

Answer:

option B) is correct

Explanation:

The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:

The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.
