Swept volume is best described as which of the following?

Explanation:
Swept volume is the space the piston moves through as it travels from top dead center to bottom dead center. It represents the cylinder displacement for one stroke—the amount of air or mixture that is drawn into or expelled from the cylinder during that stroke. You find it from the bore area times the stroke: V_swept = π × (bore/2)^2 × stroke. This volume is the difference between the total cylinder volume at BDC and the clearance volume at TDC. It’s not the space above the piston at TDC, which is the clearance volume, nor is it the piston position itself. The clearance volume stays constant and, together with the swept volume, defines the compression ratio.
