Final Answer :
B
Explanation :
Adelaide's reaction to the rattling sound is an example of the alarm phase of the general adaptation syndrome (GAS), which is the body's initial response to stress. During this phase, the body mobilizes its resources to respond to the stressor, such as releasing stress hormones like adrenaline and cortisol. The other phases of GAS (resistance, exhaustion, and chronic stress) occur after this initial alarm phase.
