The shapes of s and p orbitals are determined by which quantum number(s)?

$\text{ P. }n$

$\text{ Q. }l$

$\text{ R. }{m}_l$

The shapes of s and p orbitals are determined by which quantum number(s) is Q only i.e.$l$(azimuthal quantum number)

All electrons in an atom with the same value of are considered to belong to the same sublevels, indicates the overall shape of the orbital inside a shell and  influences orbital energies

Hence, the option B is correct.
