In a multielectron atom, which of the following orbitals described by three quantum numbers will have same energy in the absence of magnetic field and electric field : (I) n = 1, l = 0, m = 0(II) n = 2, l = 0, m = 0(III) n = 3, l = 1, m = 1(IV) n = 3, l = 2, m = 1(V) n = 3, l = 2, m = 0(a) I and II(b) II and III(c) III and IV(d) IV and V |
