Blood pressure is determined by the volume of the blood and the peripheral resistance of the blood vessels. Blood volume is dependent upon hydration level and osmotic pressure within the blood. Peripheral resistance refers to the volume of blood vessels, which is dependent upon constriction and dilation of arteries as blood flow is maximized and minimized in response to the body's needs.
Which of the following would BOTH help to raise blood pressure?

(A) Constriction of blood vessels and decreasing salt intake

(B) Dilation of blood vessels and decreasing salt intake

(C) Constriction of blood vessels and increasing salt intake

(D) Dilation of blood vessels and increasing salt intake
