Solution

The correct option is A $n$
Principle quantum no.(n) $\to$ about size and energy of orbits.
Azimuthal quantum no(l) $\to$ about shape of orbitals.
Magnetic quantum no(m) $\to$ about orientation of orbitals
Spin quantum no( $m_{s}$ ) $\to$ about direction of spin of electron in any orbitals.
These are information that can be obtained from quantum numbers.
