The question is asking which of the listed components is not necessary for spinal reflexes.

a. Interneurons: These are neurons that transmit signals between other neurons. They are a critical part of the reflex arc, which is the neural pathway that controls a reflex action.

b. Terminal effectors: These are the muscles or glands that respond to the neural signals sent during a reflex action. They are the final step in the reflex arc.

c. Motor neurons: These neurons transmit signals from the central nervous system to the terminal effectors. They are necessary for the reflex action to occur.

d. Sensory neurons: These neurons transmit signals from the site of a stimulus (like a pain signal) to the central nervous system. They are the first step in the reflex arc.

e. Peripheral receptors: These are the parts of the nervous system that detect stimuli (like pain or heat) and initiate the reflex action by sending a signal to the sensory neurons.

So, all of the components listed - interneurons, terminal effectors, motor neurons, sensory neurons, and peripheral receptors - are necessary for spinal reflexes. Therefore, the question seems to be flawed as all the options are essential for spinal reflexes.
