Show answer
Correct Option: B

AI Explanation

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

Option A) TUE - This option is incorrect because the output is not TUE.

Option B) Wed - This option is correct because the output will be "Wed".

Option C) The output is unpredictable - This option is incorrect because the output is predictable and will be "Wed".

Option D) Compilation fails due to an error on line 4 - This option is incorrect because there is no error on line 4. Line 4 declares an enum called "Days" with the values MON, TUE, and WED.

Option E) Compilation fails due to an error on line 6 - This option is incorrect because there is no error on line 6. Line 6 is a for-each loop that iterates over the values of the enum "Days".

Option F) Compilation fails due to an error on line 8 - This option is incorrect because there is no error on line 8. Line 8 creates an array "d2" and assigns the values of the enum "Days" to it.

The correct answer is B) Wed. This option is correct because the line 9 prints the value at index 2 of the array "d2", which corresponds to "Wed".
