Suppose n is a positive integer and Sn is the set of all binary strings of length n. Indicate the correct statement for the relation on S, such that for every pair (s, t) in S×S₁ satisfies s t if and only if the number of 0's in s does not exceed the number of 0's in t. (Sn) is a poset, but (Sn) is a poset and O (Sn) is not a poset. O None of these. is not a total order in S. is a total order in Sn.
