electron config question

Two electrons with the same n,l,m

a) always violate pauli principle
b) can be in different orbital of the same subshell
c) are paired
d) must be in the same atom

I choose C, because n= same shell, l= same subshell, m= same orbital so they must be paired. How is the answer B? the explanation doesn't make any sense.

omg, I thought the whole time, M means Ml= the same orbital... ehhh that cleans the question up.

so as to clarify, its B because, since they have the same spin number, then they can for example be Px Up, Py Up, having both n=2,l=1, and ML = Up right

ehh I feel so worked up about this problem now its not too bad lol I just thought M=Ml and not spins.

THats funny because I actually misread that first too. Then when no answers seemed right, I reread the Q and saw it.

Did the OP just not type the complete question in? How are you supposed to know M by itself is Ms as opposed to it being Ml? The question in the link of the first reply specifies it as Ms which makes it a clear question. I just want to make sure the OP here made a boo boo and I'm not missing something.
