Final Answer : A, Explanation :  The action potential, which is an electrical signal that travels along the axon of a neuron, does not weaken or strengthen as it travels from the skin to the brain. The strength of the signal is maintained throughout its journey, allowing for efficient and reliable transmission of information. This is due to the way in which the action potential is generated and propagated, primarily by the opening and closing of ion channels in the neuron's membrane. As a result, choice A is the correct answer.
