Below

Explanation:

Pauli exclusion principle states that no electron in an atom can have the same 4 quantum numbers. The quantum numbers are $n, l, m_{1} and m_{s}$ $n, l, m_1 and m_s$

$n$ $n$ is the principal quantum number

$l$ $l$ is the angular momentum quantum number which determines the shape of the orbital

$m_{1}$ $m_1$ is the magnetic quantum number and describes the orientation of an orbital around the nucleus

$m_{s}$ $m_s$ is the spin quantum number and has 2 possible values ie $m_{s} = \pm \frac{1}{2}$ $m_s=+-1/2$
