lexicographic prefrences

andrian
.
Let A = {0,1} x {0,1} and B = {a,b,c}. Suppose A is listed in lexicographic order based on 0 < 1 and B is in alphabetic order. If A x B x A is listed in lexicographic order, then the next element after ((1,0), c, (1,1)) is
 
(a)      ((1,0), a, (0,0))
(b)      ((l,l),c,(0,0))
(c)       ((1,1), a, (0,0))
(d)      ((1,1), a, (1,1))
(e)       ((1,1), b, (1,1))
