Hello there!
Your answer would be <u>C. dendrites to the cell body to the axon</u>
<u />
When you plug in your answer to the question, it'll say:
In transmitting sensory information to the brain, an electrical signal travels from the dendrites to the cell body to the axon of a single neuron.
The reason why C. dendrites to the cell body to the axon would be the correct answer is because the dendrites receives the signal of electricity, then sends it to the cell body (nucleus), and then is transmitting to the axon, that is conducted straight from the cell body. This whole process would transmit sensory information to the brain, in which our brain does all the time.
