Solution

The correct option is A Adrenal
The adrenal medulla secretes 2 hormones - adrenalin and noradrenalin.
Adrenalin is also called as an emergency hormone. Adrenaline brings about increased heartbeat, the rate of respiration and dilation of pupils, thereby preparing the body to face an emergency situation. Adrenalin is also called as 3F hormone because it takes care of emergency functions of the body during fear, fight, and flight. Hence, the adrenal gland is also known as 3F gland.
