During a recent flight, an executive unexpectedly received several dog and cat pictures while trying to watch a movie via in-flight Wi-Fi on an iPhone. The executive has no records of any contacts sending pictures like these and has not seen these pictures before. To BEST resolve this issue, the executive should:


A. set AirDrop so that transfers are only accepted from known contacts.
B. completely disable all wireless systems during the flight.
C. discontinue using iMessage and only use secure communication applications.
D. only allow messages and calls from saved contacts.
