**Core Concept:** Peripheral vascular resistance (PVR) is the measure of opposition to blood flow in the peripheral circulatory system. It is an essential parameter in assessing cardiovascular health and homeostasis.

**Why the Correct Answer is Right:** PVR is best determined by using the formula: PVR = (MAP - CVP) / SVR, where MAP is mean arterial pressure, CVP is central venous pressure, and SVR is systemic vascular resistance. The correct answer should be a formula that describes the calculation of PVR.

**Why Each Wrong Option is Incorrect:**

A. This option does not correctly represent the formula used to calculate PVR.
B. This option does not represent a formula for calculating PVR.
C. This option does not represent a formula for calculating PVR.
D. This option is incorrect as it does not represent the correct formula for calculating PVR.

**Clinical Pearl:** A high PVR indicates vasoconstriction, decreased cardiac output, or both, which can be seen in conditions like sepsis, pulmonary embolism, or portal hypertension.

**Correct Answer:** PVR = (MAP - CVP) / SVR
