For a 3d orbital, n = 3 (principal quantum number) and l = 2 (azimuthal quantum number, indicating the orbital shape and angular momentum).

The magnetic quantum number (m) can have integer values between -l and +l, so for l = 2, m can have values of -2, -1, 0, 1, or 2. Therefore, option E with mS = -2 is a correct set of quantum numbers for an electron in a 3d orbital.

Options A, B, C, and D all have incorrect values for either n, l, or mS.
