Choose the allowed sets of quantum numbers from the following:

Explanation

The correct answer is Option B: n = 3, l = 1, m = 0, s = +1/2. This set of quantum numbers is valid because:n (principal quantum number) can be any positive integer.l (azimuthal quantum number) can be any integer from 0 to n-1.m (magnetic quantum number) can range from -l to +l.s (spin quantum number) can be either +1/2 or -1/2.In Option A, l = 2 is not allowed for n = 2, as l must be less than n. In Option C, m = 4 is outside the valid range for l = 3. Similarly, in Option D, m = 4 is outside the valid range for l = 2.
