Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) prints one two three - This option is correct because when the program is executed, the switch statement will match the value of i1 with case 1 and execute the code block starting from case 1. The code block includes the System.out.println("one") statement. After executing the code block for case 1, the program continues to execute the code blocks for case 2 and case 3 as there are no break statements present. Therefore, the output will be "one two three".

Option B) prints one - This option is incorrect because the program will execute the code blocks for case 1, case 2, and case 3 without any breaks. So, the output will be "one two three" and not just "one".

Option C) compile time error - This option is incorrect because there are no syntax errors in the provided code. Hence, it will compile successfully.

Option D) Runtime exception - This option is incorrect because there are no runtime errors in the provided code. The code will execute without any exceptions.

Option E) None of the above - This option is incorrect because the correct answer is Option A, which states that the program will print "one two three".

The correct answer is Option A. This option is correct because the program will print "one two three" when compiled and run.
