Explanation:
The given code demonstrates slicing in Python. Slicing allows us to extract a portion of a list or string. In this case, the list `arr` contains the elements [1, 2, 3, 4, 5].
The slicing syntax for a list is `list[start:end]`. It returns a new list containing the elements from the `start` index (inclusive) to the `end` index (exclusive).
In the given code, `arr[-3:-1]` is used to slice the list `arr`. Here, the start index is -3 and the end index is -1.
Steps:
1. The start index -3 refers to the element at the third position from the end of the list, which is 3.
2. The end index -1 refers to the element at the first position from the end of the list, which is 4.
3. The slice `arr[-3:-1]` returns a new list containing the elements from index -3 (inclusive) to index -1 (exclusive), which are [3, 4].
Therefore, the output of the code is [3, 4], which corresponds to option 'B'.
