d) reticular formation.
The reticular formation is a brain structure that is responsible for the sleep-wake cycle and therefore, it is responsible for our different levels of alertness. The reticular formation has other functions but one of the main ones is the control of our state of consciousness and therefore our patterns of sleep and awareness.
In this example, Tanae was drowsy but when her child called out she immediately felt wide awake and alert. Therefore, the reticular formation (which plays a role in her arousal level and awareness) was activated.
