Dear stdent 
The angular momentum quantum number, l, (also referred to as the secondary quantum number or azimuthal quantum number) describes the shape of the orbital that an electron occupies. The lowest possible value of l is 0, and its highest possible value, depending on the principal quantum number, is n - 1.
So, l = 5-1 =4 
B is the correct option
