What statement regarding the use of lists is accurate?

Question

To analyze the statements about lists, I’ll go option by option and unpack what each claim implies about how lists behave in Python.
Option 1: 'The individual elements within a list are immutable, in that the values cannot be changed.' This is incorrect because lists are mutable in Python. You can assign to elements, e.g., my_list[0] = new_value, which demonstrates that the elements themselves can be changed. The immutability described here applies to tuples, not lists, so this statement mischaracterizes lists.
Option 2: 'Two lists cannot be concatenated together, without the creation of a third list.' This is misleading. If you use the + operator to concatenate lists, Python creates a new list as the result, which is indeed a third list. However, you can also concatenate in place using list1 += list2 (or list1.extend(list2)), which mutates the first list and does not create a new separate third list. Therefore the blanket claim that concatenation cannot happen without creating a third list is false because an in-place variant exists that does not produce a new list.
Option 3: 'A list can be sliced into sublists.' This statement is generally considered true in the sense that slicing produces a sublist (a new list containing a contiguous portion of the original). Depending on interpretation, you can also use more advanced slicing to partition a list into multiple chunks, but at the basic level, slicing yields a sublist, which supports the claim. Thus this option accurately reflects list behavior.
Option 4: 'When a list is evaluated, the elements are not evaluated.' In Python, evaluating a list literal involves evaluating its elements as expressions to construct the list, so the elements are indeed processed during creation. The phrasing implies that evaluation does not occur, which is incorrect because the elements participate in the evaluation process when the list is constructed. This makes the statement false.
