\nPressure is defined as the force acting perpendicular to a unit area ($P = F_{\\perp}\/A$). Although force is a vector, pressure is a scalar quantity because it is defined based on the magnitude of the force component normal to the surface and the magnitude of the area.
\n<\/section>\n
\nPressure at a point in a fluid acts equally in all directions (Pascal’s principle), which is characteristic of a scalar quantity.
\n<\/section>\n
\nOption A is incorrect because the definition combines vectors in a way that yields a scalar. Option B is incorrect because it doesn’t specify the component of force normal to the area. Option C accurately reflects the scalar nature of pressure by defining it using the magnitude of the normal force component per unit area.
