Final Answer:
Reflexes that involve synapses between a sensory neuron, interneuron, and motor neuron are classified as polysynaptic. Option A/B/C/D is answer.
Step-by-step explanation:
The classification of reflex arcs is based on the number of synapses involved in the neural pathway. In a monosynaptic reflex, there is a direct connection between the sensory neuron and the motor neuron, typically involving a single synapse in the spinal cord.
Polysynaptic reflexes, on the other hand, involve additional interneurons in the pathway, introducing more synapses. In the context of the given options, a reflex that includes a sensory neuron, interneuron, and motor neuron is polysynaptic. The interneuron(s) in this pathway allow for more complex and integrated responses, providing a greater level of control and modulation in the reflex response.
Option A/B/C/D is answer.
