The only requirements of set C to make is that set C must have the elements 'a' and 'c' (since set A has these two elements as well). Other than that, set C can have ANYTHING else.

So for instance, one such set could be

C = {a,b,c,e}

or it could be

C = {a,c,r,q}

or it could be

C = {a,b,c,w,x,y,z}

And it goes on. It doesn't matter as long as 'a' and 'c' are in there. So this means that C is NOT unique.

C can be any set that contains a and c, but not b or d. Therefore C is not uniquely determined.
