The quantum numbers of four electrons are given below: I. n = 4; l = 2; m₁ = -2; s = -½ II. n = 3; l = 2; m₁ = 1; s = +½ III. n = 4; l = 1; m₁ = 0; s = +½ IV. n = 3; l = 1; m₁ = -1; s = +½ The correct decreasing order of energy of these electrons is

Given below are two statements: Statement I: The Balmer spectral line for H atom with lowest energy is located at \( \frac{5}{36} R_H \text{ cm}^{-1} \). (R_H = Rydberg constant) Statement II: When the temperature of blackbody increases, the maxima of the curve (intensity of wavelength) shifts to shorter wavelength. In the light of the above statements, choose the correct answer from the options given below:
