Anne Was Down on Her Luck and Began a Plan

Anne was down on her luck and began a plan to rob a convenience store. She began watching the business during various shifts from her car across the street in order to learn the routines of the employees and develop the best plan possible. She went as far as to borrow a small surveillance camera from a friend and place it discreetly inside the store so it could be remotely monitored. On the day she planned to complete the offense she was again watching the business from the safety of her car. She started to regret her plan and decided she couldn't go through with it. She sat in her car and called a friend for some support. The employee inside had noticed the car and began feeling nervous. She subsequently notified the police. If the police question Anne about her plan which of the following may she offer in her defense?

A) factual impossibility
B) legal impossibility
C) abandonment
D) right to privacy
