Answer:
0, 1, 2
Explanation:
The rules for quantum numbers are:
n = 1, 2, 3, 4, …
l = 0, 1, 2, …, n - 1
mₗ = -l, -l + 1, …, 0, …, l - 1, l
If n = 3, l can go from 0 to 3 - 1 = 2.
The correct possible values of l are 0, 1, 2.
B is wrong because the maximum possible value of l is 2.
C and D are wrong because they contain negative numbers. They must be possible sets of magnetic quantum numbers, mₗ.
