Read the case mentioned below and answer the question :

Rahman is a successful boy, who lives in Mumbai. He is very fond of junk food but he realised that eating junk food has many ill-effects on his health. He read in a newspaper that one can control his/her eating habits in order to reach long term goals in life. After reading this article on "Healthify Life" in the newspaper, he adopted a few effective mechanisms in his own lifestyle.

He selected all necessary information about the ideal weight and body mass index and found out his extra weight that is required to be shed off with immediate effect.

He started self introspection and instructed himself about the changed diet plan and work out schedule.

He kept a self reward policy wherein be could reward his own efforts towards weight loss journey and got extra happiness with each pleasant outcome.

After applying these changes in his life, Rahman reduced his body weight and gained some extra confidence, esteem and happiness in life.

With reference to case study, even when Rahman has all means to eat junk food but he behaved the way he wanted to. Through which technique could this be made possible in this case study?

Self instruction

Rahman used self instruction to change his behavior. He talked to himself in a positive and encouraging way to help himself stay on track with his goals and avoid temptation. For example, he might have said to himself things like "I can do this" or "I'm going to be healthier and happier if I eat healthy foods."

The other options are not as accurate. Making small goals can be helpful for achieving long-term goals, but it is not specifically mentioned in the case study. Relevant information can be helpful for making informed decisions, but it is not specifically mentioned in the case study that Rahman used relevant information to change his behavior. Distraction can be a way to avoid temptation, but it is not a sustainable way to change behavior.
