I think it's the first one due to it being in order, but I'm not sure...

Took me a while to get what you are asking. It's the first.

Ok, thanks
 
The first,
[tex](A\cap B)\subset C[/tex]
is the statement that the set, [itex]A\cap B[/itex] is a subset of C.

The second,
[tex]A\cap (B\subset C)[/tex]
doen't make sense. The left side, A, is a set while the right side is NOT. The right side, [itex]B\subset C[/itex], is a statement that B is a subset of C. You can't take the intersection of a set with a statement!
