Verbal Reasoning Question on The Structure of an Atom

Consider the following pair of electrons :
1. n=3,l=1,ml=1,ms=+12  and  n=3,l=2,ml=1,ms=+12n=3, l=1, m_l =1, m_s = + \frac{1}{2}\; and \;n = 3, l=2, m_l =1, m_s=+\frac{1}{2}
2. n=3,l=2,ml=−2,ms=−12  andn=3,l=2,ml=−1,ms=−12n=3,l=2,m_l=-2,m_s=-\frac{1}{2}\;and n=3,l=2,m_l=-1,m_s=-\frac{1}{2}
3. n=3,l=2,ml=2,ms=+12  and  n=4,l=2,ml=2,ms=+12n=3,l=2,m_l=2,m_s=+\frac{1}{2}\;and \;n=4,l=2,m_l=2,m_s=+\frac{1}{2}
