The luminance of an object is the quantity that describes the amount of light produced or reflected by its surface. It is defined as the ratio between the luminous intensity, measured in candela (cd), and the square of the distance from the object to the light source, measured in meter (m). The unit of measurement of the luminance of an object is (A) $\dfrac{\mathrm{cd}}{\mathrm{m}^2}$ (B) $\dfrac{\mathrm{m}^2}{\mathrm{cd}}$ (C) $\dfrac{\mathrm{cd}}{\mathrm{m}}$ (D) $\dfrac{\mathrm{m}}{\mathrm{cd}}$ (E) $\dfrac{\mathrm{m}}{\mathrm{cd}^2}$
