The correct option is A Mineralocorticoids
The adrenal cortex can be divided into three layers, called zona reticularis (inner layer), zona fasciculata (middle layer) and zona glomerulosa (outer layer). The zona glomerulosa secretes mineralocorticoids. Zona glomerulosa makes up only 15 % of the entire adrenal cortex, yet it is the primary producer of aldosterone (the principal mineralocorticoid).
