Given the list: numbers = [5, 10, 15, 20, 25, 30] Which slice operator extracts the following three elements? [15, 20, 25]

We start by examining the given list: numbers = [5, 10, 15, 20, 25, 30]. The task is to identify which slice extracts exactly [15, 20, 25].

Option a: numbers[3:] would return elements from index 3 to the end, i.e., [20, 25, 30]. This does not match the target [15, 20, 25], so this option is incorrect.

Option b: numbers[-3:] uses negative indexing to start three elements from the end, yielding [20, 25, 30]. Since this equals the same end portion as the previous option, it also does not match the target. Therefore, this option is incorrect.

Option c: numbers[-2:] takes the last two elements, resulting in [25, 30]. This is shorter than the requested three elements and not the same sequence, so this option is incorrect.

Option d: numbers[2:5] uses a start index of 2 and a stop index of 5, which yields elements at indices 2, 3, and 4: [15, 20, 25]. This matches the required sequence precisely.

In summary, options a, b, and c all produce either different lengths or different values compared to [15, 20, 25], while option d produces exactly the desired slice. The reasoning hinges on how Python's list slicing uses [start:stop] with stop being exclusive and both indices being zero-based. Starting at index 2 captures the third element (15), and stopping before index 5 stops before the element at index 5 (30), giving exactly three elements: 15, 20, and 25.
