Answer:
B Mobile devices must be protected because they contain private information about the owner.
Explanation:
B is correct because people do need to keep their mobile device protected from people who want to take their information because a mobile can carry a lot of personal information about someone and if stolen, a person could potentially steal someone's identity. Answer A is not true because at some locations mobile devices can be very cheap. The answer is not C because mobile devices CAN be stolen because anyone could easily take your phone out of your hand and run away with it. The answer is not D because your phone could get a virus and in many cases the virus can easily steal all of your information with knowing or not knowing your password because it might be downloaded already into you device.
