$\square$ reflex.

Solution
The answer is: monosynaptic reflex.
Explanation:
A monosynaptic reflex is a simple reflex arc that involves only one synapse between the sensory neuron and the motor neuron. This is the most direct and fastest type of reflex pathway.
In this type of reflex, the sensory neuron directly synapses with the motor neuron without any interneurons involved, which is why it is called "monosynaptic" (meaning "one synapse").
An example of a monosynaptic reflex is the knee-jerk reflex, where tapping the patellar tendon leads to a direct response in the quadriceps muscle.
In summary, the correct term to fill in the blank is "monosynaptic."
