Final Answer : B, Explanation :  The strength of an action potential remains constant as it travels down an axon. This is due to the all-or-none principle, which states that an action potential either fires at maximum strength or does not fire at all. However, the speed of conduction may vary depending on the thickness of the axon and the presence of myelin.
