Following figure shows spectrum of an ideal black body at four different temperatures. The number of correct statement/s from the following is _____.

A. $$T_4 > T_3 > T_2 > T_1$$
B. The black body consists of particles performing simple harmonic motion.
C. The peak of the spectrum shifts to shorter wavelength as temperature increases.
D. $$\frac{T_1}{\nu_1} = \frac{T_2}{\nu_2} = \frac{T_3}{\nu_3}$$
E. The given spectrum could be explained using quantisation of energy
