Solution

The correct option is A $1, 0, 0, + \frac{1}{2}$
The electron of Hydrogen atom is in $1 s$ shell. Thus, $n = 1, l = 0, m = 0$ and $s = \pm 1 / 2$ . Spin quantum number can have any value of $\pm 1 / 2$ as electron can have any spin.

Thus out of given options, correct one is $1, 0, 0, \pm 1 / 2$ i.e., option B.
