A boy is walking to school when it suddenly begins raining. He runs the final few blocks to avoid getting drenched. Which of the following statements best describes how the boy’s body was able to make this response?

A. The midbrain detects and processes information from the environment and sends signals to leg muscles to change their rate of contraction.

B. Incoming information from the skin and eyes is transmitted directly to the spinal cord, which then sends a signal to the leg muscles to move faster.

C. Stimulation of cells in the eyes and skin results in signal transmission to the hypothalamus in the brain, where the signals are compared with memories and a response is made to increase leg movement.

D. Sensory receptors in the skin and eyes transmit information to the visual cortex of the brain, which processes the signal as rain and then sends a signal to the leg muscles to increase contraction.
