This gland produces the catecholamines which act in stress situations to produce a fast response throughout the body.

Complete answer:
Option A is correct. Adrenal glands are small, triangular-shaped glands located on top of both kidneys, also known as suprarenal glands. The adrenal gland secretes life-sustaining hormones. Three primary hormones are secreted by the gland: epinephrine, norepinephrine, and cortisol These three are known to be the key stress hormones that help to relieve a stressful situation. Our glands produce too many, or not enough, hormones with adrenal gland disorders.

Option B is incorrect. The hypothalamus is a minor region of the brain. It is at the base of the brain, close to the pituitary gland. The hypothalamus, although very small, plays a key role in many important functions including releasing hormones, body temperature regulators.

Option C is incorrect. The pituitary gland is called the 'master gland' because it produces the hormones that regulate so many different processes in the body. It senses the needs of the body and sends signals across the body to various organs and glands to control their activity and maintain a suitable environment.

Option D is incorrect. The thyroid gland is a crucial hormone gland: It plays a significant role in the human body's metabolism, growth, and development. It helps control many body functions by releasing a steady number of thyroid hormones into the bloodstream constantly. The metabolism influences the temperature of our body, our heartbeat, and how much one's calories are burned. If anyone has inadequate thyroid hormone, the body processes slowly.

So, the correct answer is Option A.

Note: The main insufficiency of the adrenal glands is related to disability. An autoimmune disease called Addison's disease accounts for 80%. They are unable to produce hormones when the adrenal glands get damaged.
