• A. Muscle fibre
• B. Neuron
• C. Uriniferous tubule
• D. Both A and B

Answer 1

The correct option is D Both A and B

• The all-or-none law is a principle that states that the strength of a response of a nerve cell(neuron) or muscle fibre is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fibre will fire.
• Hence All or none law is associated with muscle fibre and neuron.
• So, the correct answer is 'Both A and B'.
