ANS: A

Feedback
A Reactivity occurs when control subjects respond to the investigator not because of the treatment but because of the fact they were being studied.
B Continuing a treatment after a study is over is not necessarily related to reactive effects.
C After a treatment is finished and the study is over, concern about the use of a placebo would not be a reactive effect.
D The desire to know about study outcomes after the study is finished is not a reactive effect.
