Suppose That Dorothy and Tim Are Out to Lunch Together

Suppose that Dorothy and Tim are out to lunch together, and both are on restricted-calorie diets. Which of the following would be the best example of counter-regulation?

A) Dorothy notices that Tim has ordered a cheeseburger (and broken his diet) , and therefore she feels that she has "permission" to break her diet too. She then goes ahead and orders a cheeseburger for herself.
B) After ordering a cheeseburger for lunch, Dorothy thinks, "Well, my diet is already blown for the day; I might as well order a dessert too." She then goes ahead and orders a deluxe chocolate milkshake.
C) Dorothy orders a cheeseburger and milkshake for lunch, and thus blows her diet for the day. When Tim starts to order a similar lunch, though, Dorothy chastises him and tells him that he should try to eat a less fattening lunch.
D) After ordering a cheeseburger and milkshake for lunch, and thus blowing her diet for the day, Dorothy feels remorseful and decides to go to the gym and skip dinner that night.
