(A) According to Wien's Displacement Law,the product of the wavelength of maximum emission $\lambda_{m}$ and the absolute temperature $T$ is constant,i.e.,$\lambda_{m} T = b$.This implies $T \propto \frac{1}{\lambda_{m}}$.The wavelength of light corresponding to colors follows the order: $\lambda_{\text{blue}} Given that star $A$ is bluish,star $C$ is yellowish,and star $B$ is reddish,their wavelengths are $\lambda_{A} Since temperature is inversely proportional to wavelength,we have $T_{A} > T_{C} > T_{B}$.
