The adrenal glands produce cortisol, so if they were removed, the plasma cortisol levels would decrease. However, the removal of cortisol negative feedback would lead to increased secretion of CRH by the hypothalamus and increased secretion of ACTH by the adenohypophysis. This would ultimately result in increased secretion of other hormones (such as androgens) by the adrenal cortex, but plasma cortisol levels would remain low. Choice B correctly reflects these changes.
