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? () https://assets.asklib.com/images/image2/2018073011322911230.jpg

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.
