While working in a conference room equipped with a wireless network on a presentation document, you notice that turning your laptop in different directions results in your wireless signal strength changing. This change in signal strength is primarily caused by which RF signal property?

A.
The RF signal’s amplitude is changing due to a change in the visual line-of-sight.

B.
The RF signal’s wavelength is being affected by varying antenna gain.

C.
The RF signal’s multipath is changing the amount of RF absorbed by nearby objects.

D.
The RF signal’s phase is oscillating due to electromagnetic interference (EMI).

E.
The RF signal’s polarization is different than the receiving antenna.
