    Option C is correct. HashSet implements the Set interface and the Set interface specifies collection that contains no duplicate elements. Option A is wrong. HashSet makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time. Option B is wrong. The set can be modified. Option D is wrong. This is a Set and not a Map.
