Correct option is D

Quantum numbers could represent an electron in a 5f orbital is l=3,ml=0.

It is impossible for the main quantum number (n) to be zero. Therefore, the valid range for n is 1, 2, 3, 4, and so forth. Any integer between 0 and n – 1 may be used as the angular quantum number (l). For instance, if n = 3, l can either be 0 or 1 or 2.

Hence, option D is correct.
