The orbital magnetic quantum number, also known as the magnetic quantum number (m), specifies the orientation of the orbital in space relative to a magnetic field. It can take integer values ranging from -l to +l, where l is the orbital angular momentum quantum number. In this case, the hydrogen atom has n = 3, which means that the possible values of l are 0, 1, and 2. 
For l = 1 (p subshell), the possible values of m are -1, 0, and +1. 
For l = 2 (d subshell), the possible values of m are -2, -1, 0, +1, and +2. 
Therefore, the permitted values of the orbital magnetic quantum number for the shell with n = 3 are: 2, 1, 0, -1, and -2. 
However, the given choices include some incorrect answers and include F1F1F1S1-F1F1F101, which is not a valid value for m. 
Therefore, the best choice is C, which lists the correct values of m for the p and d orbitals in the n = 3 shell.
