Solution

The correct answer is [4, 3].

Here's the step-by-step explanation:

  1. list1 = [1, 3] creates a list with elements 1 and 3.
  2. list2 = list1 doesn't create a new list, but makes list2 point to the same list that list1 is pointing to. So, any changes made to list1 will reflect in list2 as well, because they are both pointing to the same list.
  3. list1[0] = 4 changes the first element of the list that list1 is pointing to, from 1 to 4. Since list2 is pointing to the same list, the change is reflected in list2 as well.
  4. print(list2) prints the list that list2 is pointing to, which is now [4, 3] due to the change made in step 3.
