Which method reverses the order of items in a list?

• A. reverse()
• B. sort()
• C. invert()
• D. flip()

Answer: (A)

The method that reverses the order of items in a list is the reverse() method. When called on a list, it modifies the list in place, meaning that it directly changes the original list to be in reversed order rather than creating a new list. For example, if you have a list called `my_list` containing the elements [1, 2, 3], using `my_list.reverse()` will change `my_list` to [3, 2, 1]. This functionality is straightforward and intuitively aligns with the method's name, making it clear that it simply reverses the order of the items in the list. The other methods mentioned do not reverse the order of items. The sort() method arranges the items in a list in ascending order based on their values, thus changing their order but not reversing it. The invert() and flip() methods do not exist in Python's list methods, which makes them invalid options for reversing a list's order.
