If S is an ordered set, then One of the following is true: A) If A is a subset of S and A has an upper bound, then it is not necessarily that A has a least upper Bound (Sup). B) If A is a subset of S and A has a lower bound, then A has a greatest lower Bound (inf). C) If A is a subset of S and A has an upper bound, then A has aleast Upper Bound (Sup). D) None of above.
