An advantage of choosing this implementation of "set of integers" is that adding an element to a set is a contact time operation. Which of the following is a disadvantage of this implementation?
A. Adding elements to a very small sets could cause error flags to be raised.
B. Deleting elements from very large sets mind came error flags to be raised.
C. Determining whether a set is empty will require nonconstant time.
D. Constructing the union of two sets will require quadratic time in the size of the set being constructed.
E. Deleting an element from a set will require exponential time in the size of the set from which the element is deleted.
