Debs says to John, "Hey, you sajd you would take out the trash and clean up your mess. This place looks like pigs live herel"

John says, "Leave me alone! I'll do it when I get ready." $($He storms out of the apartment$)$

Debs is still upset that John hasn't done the jobs he said he would do$,$ finds John's best friend and says, "Has John always been so messy? I don't think I can live with him."

John hears from his best friend that Debs has been talking to him about him not working to clean up the apartment. He is angry. He decides he will get back at Debs and goes home to throw things around the kitchen knowing it will make Debs really upset.

Debs comes come and sees the kitchen in complete disarray. She posts something on Facebook about how John always leaves the kitchen like a pig sty$.$

John is now really mad at the public announcement of their situation. "She didn't have to do that," he tells a friend. He goes to the apartment and starts yelling at Debs who throws his clothes off the balcony, locks the doors, and screams for John to find a new place.

This situation is an example of:

a$.$ a negative escalatory spiral

b$.$ attempts to establish a supportive climate

c$.$ avoidance spirals

d$.$ stonewalling
