Which one of the following represents a wrong set of quantum numbers for an electron in an atom? (arranged as n, l, m, and s)

$n$	$l$	$m_{l}$	$m_{s}$
2	0	0	$+ \frac{1}{2}$

n = 4, l = 0, m_{l} = 0, m_{s} = + \frac{1}{2}

n = 3, l = 1, m_{l} = 1, m_{s} = - \frac{1}{2}

n = 3, l = 2, m_{l} = 0, m_{s} = + \frac{1}{2}

n = 3, l = 0, m_{l} = 0, m_{s} = - \frac{1}{2}

n = 3, | m_{l} | = 0

m_{s} = - \frac{1}{2}
