    Explanation

    The correct answer is F.

    Carbohydrase does not fit into anything. Adrenal glands release adrenaline which can increase heartbeat rate. Ovaries produce oestrogen, leading to female secondary characteristics. Testes produce testosterone which lead to male secondary characteristics. Pituitary glands produce Antidiuretic hormone (ADH), which regulates water level in the blood. Pancreas produces insulin, which regulates blood glucose level. All these glands, hormones and functions are related to the hormonal homeostatic response.

    Carbohydrase is an enzyme, which is involved in digestion, and so does not fit into homeostatic processes.
