Imagine a person stepping on a pin and pulling his or her foot away. Look at the reflex arc of this scenario below.

Arrows in an image in the following order: receptors in skin, sensory neuron, interneuron, motor neuron, effector (muscle).

Which statement best describes the image?

The sensory nerve carries the signal from the effector to the interneuron, and the motor neuron carries the signal to the receptor.
The motor nerve carries the signal from the receptor to the interneuron, and the sensory neuron carries the signal to the effector.
The sensory nerve carries the signal from the receptor to the interneuron, and the motor neuron carries the signal to the effector.
The sensory nerve carries the signal from the receptor to the motor neuron, and the interneuron carries the signal to the effector.

"The sensory nerve carries the signal from the receptor to the interneuron, and the motor neuron carries the signal to the effector."

Explanation: receptors in skin → sensory (afferent) neuron → interneuron in the spinal cord → motor (efferent) neuron → muscle (effector) causing withdrawal.
