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) $\frac{T_1}{v_1} = \frac{T_2}{v_2} = \frac{T_3}{v_3} \neq \text{constant}$
(E) The given spectrum could be explained using quantisation of energy.
