<u>Answer:</u>
The sentence which is constructed so that the modifier clearly indicates that John works seven days a week is
Option B: John works even on weekends.
<u>Explanation:</u>
The correct sentence that shows that John works 7 days a week is Option B.  
In Option A, the words "Even works" means that John will also perform many other chores other than working on weekends. This doesn't specifically mean that John has been working all days in a week. It means that he may or may not work but he had some other chores to do. Therefore, it is incorrect.
Option C says that ‘’Even John works on weekends’’ which means that there are people other than John, who also work on weekends. So, this is also incorrect. Thus, the correct answer is Option B.
