    Your answer is correct. Quantum numbers, n and l can only take positive values.

    Where:

    n = cannot be zero

    l = any number from zero to n-1

    lm = any number between - l and + l including zero

    ms = either - 1/2 or + 1/2

    Looking at the choices, (3, 2, 1, - 1/2) is the only choice that satisfy the criteria.
