Option 3 is correct. In exposure and response prevention, the client confronts a feared trigger and refrains from the compulsion, allowing anxiety to become tolerable and often decline without washing while new safety learning develops. Option 1 is incorrect because ERP does not depend on replacing every intrusive thought with a rational thought. Option 2 is incorrect because avoiding triggers between sessions reinforces fear and prevents learning from generalizing. Option 4 is incorrect because taking extra antianxiety medication solely to suppress distress can interfere with exposure learning and should not be done without a specific treatment plan.
In-depth explanation
The therapeutic mechanism of ERP is the anxiety habituation curve: anxiety spikes during exposure, peaks within 30-60 minutes, and falls naturally if the compulsion is not performed. Each repeat exposure produces a faster, lower curve. Anything that short-circuits the curve (PRN benzo, mental rituals, reassurance-seeking) blocks therapy progress.
