Central venous pressure (CVP) is a measure of the pressure in the central veins near the heart, which reflects the amount of blood return to the right atrium. Hypovolemia, or decreased blood volume, would lead to decreased CVP due to reduced venous return. Pulmonary vascular resistance (PVR) and systemic vascular resistance (SVR) may increase in the setting of hypovolemia, as the body attempts to maintain blood pressure and compensate for reduced blood volume. However, these parameters are not as directly affected as CVP. Therefore, the best choice is A.
