MHT CET Physics question

Three black discs 'x', 'y', 'z' have radii 1m, 2m and 3m respectively. The wavelengths corresponding to maximum intensity are 200, 300 and 400 nm respectively. The relation between emissive powers 'E', 'E' and 'E' is [MHT-CET 2023]

• (A)E > E > ECorrect
• (B)E < E < E
• (C)E = E = E
• (D)E > E > ECorrect
