The symbol "l" indicates orbital quantum number that describes the shape of the orbital. Of the options given, those are the magnetic quantum numbers that indicates the number of orbitals is often a range of values from negative to positive. 2l + 1 is the formula to find the number of orbitals. l = n -1, where n is the principal quantum number. Therefore, l = 2, MY = (-2, -1, 0, 1, 2) or 5 orbitals.
