ANF (Atrial Natriuretic Factor) is a peptide hormone produced by the right atrium of the heart in most mammals. It is an important component of circulatory regulation.
When there is an increase in the blood flow (volume) and blood pressure to the atria of the heart, the release of ANF (atrial natriuretic factor) is caused. Its release causes vasodilation and a decrease in the blood pressure. Thus, it works oppositely to renin-angiotensin mechanism by inhibiting the release of renin.
Hence, option (2) is correct.
