This illustrates that there is no communication in the relationship. John is guessing why Mary is coming home late, yet he is not asking Mary why. His assumption may be from things that have happened in the relationship such as loss of intimacy, no talking, doing things separate now whereas in the past it was more of a companionship and close-knit relationship shared with outings and dinners at the table. BUT, until John asks Mary why she is late, his speculation is just a guess. He could be right, but he could be wrong. Maybe she is working on a project that is taking longer, maybe someone quit so she is having to do their job as well as her own. Regardless, communication is the key in all relationships and without it, relationships will fail.
The correct answer is framing.
