D Correct answer
Explanation

This is the correct choice. The for statement, for (String ss: table), is executed one time for each of the three elements in table. The output comes out to be : aa, 0aa, 1aa, 2bb, 0bb, 1bb, 2cc, 0cc, 1cc, 2. So, “aa” will be printed 3 times, hence this answer is correct.
