- B. Knee-jerk stretch reflex
- C. Foot withdrawal by painful stimulation
- D. Hand withdrawal when touched by a hot object
Explanation
The knee-jerk stretch reflex is the correct answer because it is a monosynaptic reflex, where the sensory neuron directly communicates with the motor neuron in the spinal cord without the involvement of interneurons. The pupil reflex, foot withdrawal, and hand withdrawal are all polysynaptic, involving multiple synapses and more complex neural pathways.
