Choose whichever quantum number it is below.

#### Explanation:

The principal quantum number, $n$ would be $n = 2$

The angular quantum number, $l$, describes the sublevels in $n$ and the orbital shapes.
So $n = 2$ has 2 sublevels called 2s and 2p
i.e. angular quantum number= 2

The magnetic quantum number, $m$ describes the number of orbitals withing a sublevel.

So the $p$ sublevel in $2 p$ has 3 orbitals (with up to 6 elecrons) ie. magnetic quantum number= 3
