Question

Which of the following processes enables a cell phone to receive communications from a cell phone tower?
A.
Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.
B.
Electromagnetic waves from the tower are reflected by the cell phone, producing an electromagnetic field that is detected by the internal circuits of the phone.
C.
Electromagnetic waves diffract around the cell phone's antenna, which allows the waves to be detected by the internal circuits of the phone.
D.
Electromagnetic waves from the tower interfere with the radio waves emitted by the cell phone, producing electric currents in the internal circuits of the phone.
