The correct option is B ANP
In response to high blood volume, secretion of ADH and Atrial Natriuretic Peptide (ANP) will increase, lowering blood volume. ADH constantly regulates and balances the amount of water in your blood. It is released by muscle cells in the upper chambers (atria) of the heart (atrial myocytes) in response to high blood volume. ANP acts to reduce the water, sodium thereby reducing blood pressure.
