The diagram above depicts the response to a pinprick (stimulus) on the tip of a human finger. The arrows show the direction of impulse transmission along the labeled axons. If axon II was damaged before the pinprick, which of the following is most likely?

Axon II connects the brain to the response. If this axon is damaged, the stimulus will be felt, but the brain would be unable to send a signal back to the finger, resulting in a lack of response.
