Answer:
The correcto answer is Aversive conditioning.
Explanation:
Aversive conditioning in psychology is defined as a procedure which uses an unpleasant stimuli or a punishment to stop an unwanted behavior or reduce the frecuency of it. For example, when children have nail bitting habits a transparent nail nail polish with a bitter taste is applied to give the averisve stimuli desired in order to end this habit. In Janet's case the bitter tasting chocolate is the aversive stimuli to prevent her from eating chocolate and ultimately controlling or atleast reducing her cravings, therefore aversive conditioning is the treatment used in her case.
