Solution

The correct option is D Both Assertion and Reason are incorrect
The outer layer of adrenal is called adrenal cortex. This part of adrenal is vitally important for life and its destruction or removal kills the animal. It secretes a number of steroid hormones which are broadly classified into three groups, viz glucocorticoids, mineralocorticoids and sex corticoids. Glucocorticoids regulate the metabolisms of carbohydrate, fats and proteins. Mineralocorticoids regulate the balance of water and electrolytes is our body. Sex corticoids stimulate the development of external sex characters.
So, the correct answer is 'Both Assertion and Reason are incorrect'.
