Which of the following is not a valid set of quantum numbers?

For a given principal quantum number n, the angular momentum quantum number l must be an integer from 0 through n − 1. When n = 3, l can only be 0, 1, or 2, so l = 3 is not allowed in choice C. Choices A and B satisfy this rule, and their magnetic quantum numbers m are within the allowed range from −l to +l.
