I THINK FALSE!! BECAUSE AN IN THE ARTICLE DOEN'T MEAN TO SHOW IT PRECEDES AS A GENERAL PERSON.
I believe the correct sentence should be; “Why do you think the visitors didn’t obey the rules?” Mother asked. A question mark is needed for the question and Mother must be capitalized.
I would say B but if I'm wrong it's D.
Hope This Helps! Have A Nice Weekend!!
I think the answer is A, or D, have a nice day!!!
