The power radiated by a black body is P and it radiates maximum energy at wavelength,radiates maximum energy at wavelength,$$\lambda_{0}$$ If the temperature of the black body is now changed so that it radiates maximum energy at wavelength $$\frac{3}{4} \lambda_{0}$$, the power radiated by it becomes nP. The value of n is

A

$$\frac{81}{256}$$

B

$$\frac{256}{81}$$

C

$$\frac{4}{3}$$

D

$$\frac{3}{4}$$
