Charles was one of three employees who had access to some very sensitive computer-based data that was discovered to have been copied without permission. The data could provide a competitor with significant business advantage over the company, and the company suspected that one of the three was engaged in selling the information. The three were called into a conference room, then each placed in separate rooms. They were told that they were the employees with access to the data, and that someone had copied it. Security personnel were placed at the door to each of the three rooms, and the employees were each questioned separately by various managers and investigators. After six hours, the employees were told they could go home and report back to work as usual the next day.

Which of the following is most correct?

A. The use of security personnel at the doors of the rooms containing the employees tends to make the employer liable for claims by the employees.

B. Keeping the employees in the rooms for six hours tends to make the employer liable for claims by the employees.

C. Both A and B are true.

D. Neither A nor B are true.
