When Lacey was stressed by bus delays,what was being released by her adrenal gland

A)  corticosteroids 
B)  dopamine 
C)  ACTH 
D)  serotonin

When Lacey was getting angry and worked up about the bus delays before, it is likely that her adrenal gland was releasing corticosteroids. This stress hormone is released by the adrenal gland in response to stressors, such as delays and frustration. Corticosteroids can cause physical symptoms such as headaches, and can also contribute to feelings of irritability and agitation. By finding a way to distract herself and prevent boredom during the delays, Lacey is likely reducing the amount of corticosteroids her body is producing and therefore experiencing fewer negative physical and emotional effects.
