3. What is the result of the following code? (50 Points) 1st=[5,10,15,20] 1st[1:3]=[25,30] print(lst) B) [5,25,30,15,20] [25,30] A) [5,25,30,20] D) [5,10,25,30,20]

The correct answer is D) .Explanation:The given code creates a list named "lst" with the elements [5, 10, 15, 20]. Then, it replaces the elements at indices 1 and 2 with the elements 25 and 30, respectively. Finally, it prints the modified list.The code can be broken down as follows:1. creates a list named "lst" with the elements [5, 10, 15, 20].2. replaces the elements at indices 1 and 2 with the elements 25 and 30, respectively. In Python, the slice notation [1:3] specifies that we want to replace the elements at indices 1 and 2 (i.e., the second and third elements in the list).3. prints the modified list.Therefore, the result of the code is the list [5, 10, 25, 30, 20], which corresponds to option D.
