Answer: B

Explanation:

The broadcast signal from a wireless access point can be affected by various factors, such as distance, obstacles, interference, and configuration. One of the possible causes of weak signal strength is electromagnetic interference (EMI), which is the disruption of wireless communication by devices or objects that emit electromagnetic waves, such as microwaves, cordless phones, power lines, or fluorescent lights. To improve the signal strength, the user should ensure that sources of EMI are removed or relocated away from the wireless access point and the wireless devices78.
