<span>A.
Antoine brushed his teeth before he eats his breakfast.
Take a look at the bolded words:
</span><span>Antoine brushed his teeth before he eats his breakfast.</span>

It is a inappropriate shift in tense.
Final answer: A
The correct answer should be B. living with others
J.K. Rowling is the author of Harry Potter
