Sets in many programming languages, including Python and Java, do not maintain elements in a specific order like lists or arrays do. Instead, the order is determined by the set's implementation (e.g., hash sets or tree sets). Therefore, when iterating over a set, elements are visited in the order maintained by the set, which might not be the order in which elements were added. Options A, B, and D are incorrect because: A) Typically, trying to remove a non-existent element from a set does not cause an exception; the set remains unchanged. B) Adding an existing element to a set does not cause an exception; the set simply remains unchanged because sets do not allow duplicate elements. D) Sets do not support adding elements at a specific position because sets do not maintain a sequence of elements like lists or arrays do.
