The correct option is A Cortisol
Cortisol is a steroid hormone, known as a glucocorticoid, made in the cortex of the adrenal glands and then released into the blood which transports it all round the body. It is a life-sustaining hormone which maintains homeostasis. Almost every cell contains receptors for cortisol and so cortisol can have lots of different actions depending on which sort of cells it is acting upon. These effects include controlling the body’s blood sugar levels and thus regulating metabolism, acting as an anti-inflammatory, influencing memory formation, controlling salt and water balance, influencing blood pressure and helping the development of the foetus. In many species, cortisol is also responsible for triggering the processes involved in giving birth. Aldosterone, parathormone, and somatostatin do not cause the symptoms such as obesity, weakness, salt and water retention etc. Thus, option A is correct.
