Correct Answer is D
Explanation
Choice A rationale
An insufficient amount of triiodothyronine (T3) and thyroxine (T4) would lead to hypothyroidism, not Addison’s disease.
Choice B rationale
Decreased levels of all the adrenocortical hormones could lead to various symptoms, but the most severe manifestations of Addison’s disease are specifically caused by an insufficient amount of circulating cortisol.
Choice C rationale
Deficiencies in the renin-angiotensin system could affect blood pressure regulation, but they would not cause the most severe manifestations of Addison’s disease.
Choice D rationale
An insufficient amount of circulating cortisol is indeed what causes the most severe manifestations of Addison’s disease. Cortisol is a hormone that helps your body respond to stress, including the stress of illness, injury or surgery. It also helps maintain your blood pressure, heart function, immune system and blood glucose (sugar) levels.
