Is my answer correct?
which of the following is a possible set of quantum numbers for an electron (n, l, m subscript l, m subscript s) ?

(1, 0, 0, +1)

(2, 2, 1, + 1/2 )

(4, -3, 0, - 1/2 )

(3, 2, 1, - 1/2 )< my answer

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

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
