A man taking 20 cigarettes per day, staed coughing, his family suggested quitting cigarettes. He is ready to quit but think that quitting will make him irritable, the best health planning model followed is:

C. i..e Precontemplation and preparation- A chronic smoker is aware that a problem (of smoking) exists and he is seriously thinking (contemplating) about overcoming it but has not yet made a commitment to take an action (as he is reluctant). So the patient is in the contemplation stage of behavior change. He reached this stage b/o pros-cons /gain - loss/ benefit-cost analysis regarding his sickness susceptibility (not cost factor) i.e. chronic cough.- Miller and Rollnick's Motivational enhancement therapy (MET) using transtheoretical model of change for quitting problem behavior (habit) such as smoking alcoholism, drug addiction or eating disorder (anorexia) has 6 stages (wheel) of change (proposed by Prochaska and C. DiClementi)- pre-contemplation, contemplation, preparation, action, maintenance, and relapse prevention (termination).
