Correct option:(1)Atrial Natriuretic Factor

Explanation:

A decrease in blood pressure / volume stimulates the release of renin, aldosterone, and ADH.

Increase in blood pressure / volume stimulates the release of Atrial Natriuretic Factor (ANF) which
cause vasodilation.

Also inhibits RAAS (Renin Angiotensin Aldosterone System) mechanism that decreases the blood volume/pressure.
