9. Rick, a 30-year old XY subject, was in a car accident three weeks ago. Although Rick got a blunt hit to his sides, he did not feel that he needed to be taken to an ER. Instead, he took a week of rest at home. But, when he returned to work, he started feeling week, developed salt-craving and patches of darkness in the skin, and began to faint. Rick's doctor suspected these symptoms to Blunt force-induced Adrenal Insufficiency.

a. normal: normal: normal

b. below-normal: below-normal: above-normal

c. above-normal: above-normal: above-normal

d. normal: below-normal: above-normal

e. below-normal: below-normal: below-normal
