Peter woke up in the middle of night in darkness. Without being able to see, he was able to make his way to the bathroom without running into any objects in his path.

Which of the following best describes how he is able to do this?

A. Peter's brain received visual information from sensory receptors other than his eyes, so there was no change in how his body responded to the darkness around him.

B. Peter's brain used only stored memories as input when he moved through the darkness, as all sensory receptors are directly tied to the visual system.

C. Peter's brain still received messages from his other sensory receptors, which his brain combined with stored memories in order to move through the darkness.

D. Peter's brain used only messages received from his other sensory receptors when he moved through the darkness, as the visual system is not an important part of the central nervous system.​
