I believe it is the first option
There are two phases of the cardiac cycle. These phases are diastole and systole. The dicrotic notch is found during systole, specifically ventricular systole.
Systole is the time when <span>left and right ventricles contract and eject blood into the aorta and pulmonary artery.

Diastole is the time when the ventricles are not contracting or are in a relax mode.
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.
