D Correct answer
Explanation

The variable i will have the values 0, 1 and 2. When i is 0, nothing will be printed because of the break in case 0. When i is 1, one two three will be the output because case 1, case 2 and case 3 will be executed (they don't have break statements). When i is 2, two three will be the output because case 2 and case 3 will be executed (again no break statements). Finally, when the for loop finishes done will be output.
