Answer:
zona glomerulosa
Step-by-step explanation:
Aldosterone is synthesised in the adrenal gland's region zona glomerulosa, which is lying directly beneath the renal capsule.
It controls the excretion of electrolytes and intravascular volume primarily through its effects on distal tubules and cortical kidney collection ducts, in which it serves to increase potassium excretion and sodium reabsorption.
Hence, the correct otpion is zona glomerulosa.
