Refer to the exhibit. The signal transmitted from the AP is reflected off a wall resulting in multipath interference at the client end.
Which statement is true？（）

A. The transmitted signal from the AP arrives at the client at slightly different times resulting in phase shifting.
B. If signal 2 is close to 360 degrees out of phase with signal 1， the result is essentially zerosignal or a dead spot in the WLAN.
C. Multipath interference is less of an issue when using a DSSS technology because multipath is frequency selective.
D. If signal 1 is in phase with signal 2， the result is essentially zerosignal or a dead spot in the WLAN.
E. Multipath interference is solved by using dual antennas.
