Selected Answer: C
1. You start with the list `l1 = [1, 2, 3]`. 2. You iterate through the range of the length of `l1`, which initially is 3. 3. During each iteration, you insert the value at the current index `v` into the second position of the list (index 1). Here's the detailed iteration breakdown: - Initial `l1 = [1, 2, 3]`. - The length of `l1` is 3, so the range is `range(3)` which is `[0, 1, 2]`. ### Iteration 1 (v = 0): - `l1[0]` is 1. - Insert `1` at position `1`. - `l1` becomes `[1, 1, 2, 3]`. ### Iteration 2 (v = 1): - `l1[1]` is 1. - Insert `1` at position `1`. - `l1` becomes `[1, 1, 1, 2, 3]`. ### Iteration 3 (v = 2): - `l1[2]` is 1. - Insert `1` at position `1`. - `l1` becomes `[1, 1, 1, 1, 2, 3]`. Finally, the list `l1` is `[1, 1, 1, 1, 2, 3]`.
