Explanation

Zona glomerulosa : The outer thin layer constitutes about `15%` of adrenal cortex, and secretes mineralocorticoids.
Zona fasciculate : The middle widest layer constitutes about `75%` of adrenal cortex and secretes glucocorticoids such as cortisol, cofticosterone and trace amounts of adrenal androgen and oestrogen.
Zona reticularis : The inner zone of adrenal cortex constitute about `10%` of adrenal cortex and secretes the adrenal androgen, trace amount of oestrogen and glucocorticoids.
