Pretty confident that it is A, judging by that the word composition is used as a combination or a ratio of 2 things. Also none of the other options make sense.
I have a question. Where are "which of these?"
Answer:
It is a motor reflex response
Explanation:
This motor reflex is carried out by motor neurons which are located in the Brain and spinal cord. They are of two types, the upper motor neuron and the lower motor neuron. They upper motor neuron connects with the lower motor neuron in the transmission of impulses. Their presynaptic tract is in the cerebral motor area via the corticospinal tract while their post synaptic tract is in muscle fibres. Thus when she hit her legs on the glass, afferent fires was sent to the brain which then sent efferent impulses to the muscle fibers to quickly withdraw the leg due to action of motor neurons.
The long term probably has more experience people and the short one would probably not have some resources u need
