Correct Answer: Adrenal

Solution : The correct option is Adrenal.

The adrenal glands play a role in regulating blood pressure through the production of hormones such as aldosterone and adrenaline (epinephrine). Aldosterone, specifically, is produced by the adrenal cortex and is involved in the regulation of sodium and potassium levels in the body, which can influence blood pressure. Hormones produced by the adrenal glands, like aldosterone and adrenaline, can influence blood pressure, but they are just one part of the overall regulatory system.
