twinklehello so technically out of all of the options it is the best-suited one,
A- this one doesn't really make sense bc its both action and contemplation
B- I think this one would be between pre-contemplation and contemplation
c- this one is contemplation and then relapse
d- this one is the most correct, (and my teacher's PowerPoint says that an individual in the preparation stage can make some behavioural changes but doesn't completely change their behaviour. )
I hope this makes sense, and if anyone has anything to add please do!
