Show Suggested Answer

Suggested Answer: D

You can't really say anything because you don't know what the unit tests are testing and whether they are correctly representing whether the application is working correctly. However, if all the tests passes you didn't break any already existing tests. Also, if none tests existed yet, you did not break them.
