ArrayLists are efficient for random access of elements, meaning reading elements at any position in the list is fast. Options A, B, and C involve operations that require shifting elements, which is costly in an ArrayList due to its underlying array structure. Reading elements, as described in option D, does not involve shifting, making it efficiently executed on an ArrayList.
