The Magnetic quantum number for 4f orbital would be _____?

-3, -2, -1, 0, +1, +2, +3

-2, -3, -1, 0, +2, +3, +1

-3, -4, -2, -1, 0, +3, +2, +1

None of these

The magnetic quantum number ( $m_l$ ) defines the orientation of orbitals and ranges from $-l$ to $+l$

For the 4f orbital, $l = 3$ , so $m_l$ values are -3, -2, -1, 0, +1, +2, +3.
