Verified step by step guidance

Understand the concept of a monosynaptic reflex arc: A monosynaptic reflex arc involves only one synapse between two neurons, which are typically a sensory neuron and a motor neuron.

Identify the role of each neuron type: Sensory neurons carry signals from sensory receptors to the central nervous system, while motor neurons carry signals from the central nervous system to effectors such as muscles.

Recognize that interneurons are not involved in a monosynaptic reflex arc: Interneurons are present in polysynaptic reflex arcs, where they connect sensory and motor neurons, adding additional synapses.

Analyze the options given: The correct pair for a monosynaptic reflex arc should include only a sensory neuron and a motor neuron, without the involvement of an interneuron.

Conclude that the synapse between a sensory neuron and a motor neuron is the only option that forms a monosynaptic reflex arc, as it involves a direct connection without any interneurons.
