Answer : c

Hints & Solutions

(c) Adrenal gland has two parts-cortex and medulla. The medulla is stimulated by sympathetic nervous tissue to produce adrenaline and non-adrenaline while the cortex is stimulated by pituitary hormone to release cortisol, aldosterone and estrogens. Thus injury to adrenal cortex is not likely to affect the secretion of adrenaline.
